All kinds of exciting projects, such as <a href=\"http:\/\/polygraph.cool\/\" target=\"_blank\">Polygraph<\/a>, are pushing the boundaries. Some are very insightful, while others can be classed as more expressive data art. However, if you\u2019re new to data visualisations, it all can feel a little overwhelming. <\/p>\n<p>Where do you start? And what kind of principles should you consider? To help you create better data visualisations, we talked to some leading experts and asked them for their tips and advice on best practices. Here\u2019s what they had to say. <\/p>\n<h3>Focus on the idea, not the tool<\/h3>\n<p>UX designer and strategist <a href=\"http:\/\/catherinemaddenrelay.com\/\" target=\"_blank\">Catherine Madden<\/a> recommends, rather than getting hung up on the tools you need to use and\/or learn, you should focus on the idea: \u201cIf possible, worry about execution only once you have a great concept and outline.\u201d<\/p>\n<p>Data visualisation designer <a herf=\"https:\/\/www.visualcinnamon.com\/\" target=\"_blank\">Nadieh Bremer<\/a> agrees. Even when you explore the tools, don\u2019t trust that the default of charting tools is the best. \u201cThese have often been thought up by developers, who can do amazing things, but they typically don&#8217;t know any visualisation best practices.\u201d<\/p>\n<p><em>(As an aside, Heart Internet is proud to announce that we\u2019ll be sponsoring <a href=\"https:\/\/pixelpioneers.co\/events\/bristol-2017\" target=\"_blank\">Pixel Pioneers Bristol<\/a> on 22 June. This one-day conference on web design and development will feature Nadieh Bremer giving a talk on how to create better data visualisations.)<\/em><\/p>\n<h3>Follow graphic design principles<\/h3>\n<p>Designer and creative coder <a href=\"http:\/\/www.kultur.design\/\" target=\"_blank\">Mike Brondbjerg<\/a> argues that your designs should work at the service of the data if you want to create insightful visualisation projects and make them clear and accessible. <\/p>\n<p>\u201cFollow principles of good graphic design,\u201d he suggests. \u201cMake sure everything in your graphic supports what you trying to communicate, doesn&#8217;t distract, confuse or obfuscate the data. Get rid of everything that is superfluous. And if possible always make your data and process available to the viewer for further analysis and understanding.\u201d<\/p>\n<p align=\"center\"><div id=\"attachment_16572\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-16572\" src=\"https:\/\/www.heartinternet.uk\/blog\/wp-content\/uploads\/visualisation-diabetes.png\" alt=\"Diabetes data visualisation by Mike Brondbjerg for Bite Medical and Abbott\" width=\"800\" height=\"450\" class=\"size-full wp-image-16572\" \/><p id=\"caption-attachment-16572\" class=\"wp-caption-text\">Uncluttered diabetes data from <a href=\"http:\/\/www.kultur.design\/portfolio\/abbott-diabetes\/\" target=\"_blank\">a project for Bite Medical &#038; Abbott<\/a> by Kultur Design, Mike Brondbjerg\u2019s agency<\/p><\/div>\n<h3>Avoid visual clutter<\/h3>\n<p>Nadieh Bremer recommends either using an axis or labelling your data points directly (eg the bars in a bar chart). <\/p>\n<p>\u201cUsing both is overkill,\u201d she warns. \u201cPersonally, I prefer an axis, and perhaps, if one value is really important, label that for visual distinction. But in general more text in a chart functions as visual clutter that takes away our skill to easily see trends.\u201d<\/p>\n<p>Bremer also points out that axes and tick marks don&#8217;t need to be 2px pure black. \u201cMake them thin and grey,\u201d she suggests, \u201cthey&#8217;re only there for assistance. Your eyes should be drawn to the data, not the axes. Also, grid lines aren&#8217;t needed as often as you think.\u201d<\/p>\n<p align=\"center\"><div id=\"attachment_16573\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-16573\" src=\"https:\/\/www.heartinternet.uk\/blog\/wp-content\/uploads\/visualisation-translate.jpg\" alt=\"A data visualisation by Nadieh Bremer with Google Translate data\" width=\"800\" height=\"333\" class=\"size-full wp-image-16573\" \/><p id=\"caption-attachment-16573\" class=\"wp-caption-text\">Nadieh Bremer recently collaborated with Google for <a href=\"http:\/\/www.beautifulinenglish.com\/\" target=\"_blank\">a data visualisation project that used Google Translate data<\/a><\/p><\/div>\n<h3>Sketch out ideas<\/h3>\n<p>\u201cTake some time to sit back and think about your data and what goal\/question it is going to answer,\u201d Bremer advises. \u201cThen sketch out ideas on plain paper to not let yourself be constricted by the limitations of your tool.\u201d<\/p>\n<p>Catherine Madden agrees: \u201cSketch, sketch, sketch! I know not everyone can draw very well, but there is simply no better way to achieve clarity and think creatively.\u201d<\/p>\n<p>\u201cStart with a mind map. Then sketch out some SFDs (Shitty First Drafts), for example on an iPad, to get them out of your system. Show people in your target audience your favourite draft concepts and listen for the questions they have. Then build something to answer those questions. Return to your mind map or SFDs as needed.\u201d<\/p>\n<p align=\"center\"><div id=\"attachment_16575\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-16575\" src=\"https:\/\/www.heartinternet.uk\/blog\/wp-content\/uploads\/visualisation-jobs.png\" alt=\"A data visualisation by Catherine Madden on the future of jobs\" width=\"800\" height=\"600\" class=\"size-full wp-image-16575\" \/><p id=\"caption-attachment-16575\" class=\"wp-caption-text\">All of Catherine Madden\u2019s projects start with a mind map, using only information and questions in her own mind. This one\u2019s for <a href=\"http:\/\/catherinemaddenrelay.com\/blog\/2017\/5\/5\/jobs-of-the-future-project\" target=\"_blank\">a project on the Future of Jobs<\/a>.<\/p><\/div>\n<h3>Figure out users and their needs<\/h3>\n<p>For <a href=\"http:\/\/sxywu.com\/\" target=\"_blank\">Shirley Wu<\/a>, a software engineer that specialises in data visualisation for the web, one of the biggest lessons she\u2019s learned is to figure out the user and their needs when developing for product. <\/p>\n<p>\u201cThat might be confusing at first,\u201d she explains, \u201cbecause oftentimes what the user says is actually what they want, and the key is to dig in and figure out what they need underneath all of that. Then, design with those needs in mind. I find data visualisations for product really challenging, because the data is often vast and ever-changing. So having those specific needs in mind will help focus the visualisation design, and also make identifying edge cases with the data easier.\u201d<\/p>\n<h3>Design with scale in mind<\/h3>\n<p>Wu also stresses that building out data visualisations for products isn&#8217;t just a front-end job. <\/p>\n<p>\u201cIt also requires a backend team that can deftly munge the data and feed them to the front-end for display,\u201d she argues. \u201cSo even if you aren&#8217;t starting out with big sets of data, design with scale in mind. When that dataset does eventually get big, hopefully both the front- and back-end teams won&#8217;t have to refactor a lot to accommodate.\u201d<\/p>\n<h3>Dive deep into the data<\/h3>\n<p>Wu also creates one-off visualisations and is one half of <a href=\"http:\/\/www.datasketch.es\/\" target=\"_blank\">Data Sketches<\/a>, a data visualisation collaboration with Nadieh Bremer.<\/p>\n<p>\u201cI find designing one-off visualisations a lot more fun because the dataset is often unchanging and thus you can find insights in the data to weave into a story,\u201d she enthuses. \u201cSo the priority there is to first identify the ideas, questions, or hypothesis you have about the data, and explore with those questions in mind &#8211; again, so that you can keep your designs focused. Once you&#8217;ve explored and gotten a sense of the data &#8211; looked into the extremes, the attributes of the data, any interesting insights or tidbits to share &#8211; then you can start sketching your ideas, thinking about what visual encodings to use, etc. Also switch back and forth when coding out those sketches, and sketching out your ideas, because (especially with larger datasets) oftentimes there are insights you won&#8217;t find until you really see the data displayed on the screen.\u201d<\/p>\n<p>Don&#8217;t assume that an excellent dataset should be your starting point and anchor, however. \u201cSometimes having access to lots of data can distract you from the ultimate goal,\u201d warns Catherine Madden.<\/p>\n<div id=\"attachment_16577\" style=\"width: 810px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-16577\" src=\"https:\/\/www.heartinternet.uk\/blog\/wp-content\/uploads\/visualisation-trends.png\" alt=\"A data visualisation by Shirley Wu with Google Trends data\" width=\"800\" height=\"521\" class=\"size-full wp-image-16577\" \/><p id=\"caption-attachment-16577\" class=\"wp-caption-text\">Shirley Wu also recently collaborated with Google News Lab and opted to explore Google Trends data. Check out <a href=\"http:\/\/www.datasketch.es\/\" target=\"_blank\">Data Sketches<\/a>, her project with Nadieh Bremer.<\/p><\/div>\n<h3>Explore different ways of displaying the data<\/h3>\n<p>When coding out your visualisations, don&#8217;t be limited by the examples out there. Wu suggests to pick and choose what fits best for your data. \u201cThat might mean learning SVG, and especially the SVG path commands, to bring your sketches to life.\u201d<\/p>\n<p>And when a project\u2019s purpose is more about producing art than insight, you can be much more free with how you display your data, argues Brondbjerg. <\/p>\n<p>\u201cTry and find data that is meaningful and personal to you, visually interesting, and explore different of ways of expressing and encoding the data&#8230; variation of colour, shape, movement, proximity and relationships etc. Abstracting data for art and illustration is fine, but always use data that is appropriate, and whatever your project, never set out to mislead the viewer&#8230; I think we&#8217;ll all agree there&#8217;s already enough fake news around!\u201d<\/p>\n<h3>Take inspiration from others<\/h3>\n<p>Nadieh Bremer also recommends stealing like an artist. <\/p>\n<p>\u201cLook at what other people have done and see if you can fit your data into any of their forms,\u201d she suggests. \u201cIf yes, does it show insights? Make adjustments to the design to make it fit your topic and style more.\u201d<\/p>\n<p>Whatever you do, get feedback early and often. Catherine Madden recommends: \u201cPrioritise input you receive from your target audience over others.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The field of data visualisations has expanded rapidly in recent years.
