Hi Friends -

Welcome to issue 219 of the Weekly Newsletter.

  • Data Humanism, the Revolution will be Visualized
    We’ve reached Peak Infographics. Are you ready for what comes next?...Now that we are past what we can call peak infographics, we are left with a general audience that understands some of the tools needed to welcome a second wave of more meaningful and thoughtful visualization...visual design — with its power to instantly reach out to places in our subconscious without the mediation of language, and with its inherent ability to convey large amounts of structured and unstructured information across cultures — is going to be even more central to this silent but inevitable revolution...

  • One Dataset, Visualized 25 Ways
    “Let the data speak.” It’s a common saying for chart design. The premise — strip out the bits that don’t help patterns in your data emerge — is fine, but people often misinterpret the mantra to mean that they should make a stripped down chart and let the data take it from there...To show you what I mean, I present you with twenty-five charts below, all based on the same dataset. It’s life expectancy data by country, it’s from the the World Health Organization and it spans 2000 to 2015. Each chart provides a different focus and interpretation...
  • A Visitor’s Guide To
    5th February 2017, marked seven years since I launched It genuinely feels like only yesterday when I first clicked on 'Add New' and began the long journey towards composing over 750 posts...Therefore, to mark this anniversary, I decided to compile a brief guide to new or infrequent visitors to help them understand what is about, to profile some of the main content you can expect to find on the site (both now and in the future), and to share some reflections on my own journey through this period as a site editor...
  • The State of Information Visualization, 2017
    Between Surprise Maps, Dear Data, and election graphics, 2016 was an exciting year. There have also been some gaps, however, notably around storytelling. How far have we come, and where is visualization going?...
  • A Short History Of Color Theory
    Although a basic understanding of the color spectrum is rather easy to develop, color theory is an almost infinitely complex subject with roots in both science and art. It can therefore be a daunting task to learn about color composition in a way that is true to both art history and scientific truth...

D3.js Reading and Videos

  • Scatterplot Matrix Brushing d3v4
    mbostock’s Scatterplot Matrix Brushing, ported to d3v4 by @Fil...The scatterplot matrix visualizations pairwise correlations for multi-dimensional data; each cell in the matrix is a scatterplot. This example uses Anderson's data of iris flowers on the Gaspé Peninsula. Scatterplot matrix design invented by J. A. Hartigan; see also R and GGobi. Data on Iris flowers collected by Edgar Anderson and published by Ronald Fisher...
  • Command-Line Cartography, Part 4 - A tour of d3-geo’s new command-line interface.
    This is Part 4 of a tutorial on making thematic maps from the command line using d3-geo, TopoJSON and ndjson-cli...As in Part 2, a reasonable starting point is a sequential scale with a perceptually-motivated color scheme such as Viridis. However, now we will apply ndjson-map to the feature collection as a single entity, rather than evaluating the expression independently for each feature; this allows global operations, such as computing the maximum density of any tract...

Hope that you had a great past month and that next month is even better!

Wishing you the best,
