Data Visualization and D3.js Newsletter Issue 164 Weekly Data Visualization and D3.js Newsletter

Hi Friends -

Welcome to issue 164 of the Weekly Newsletter.

Onwards to this week's links...


  • From Anscombe's Quartet To Choropleth Classification
    There's a good chance that if you're into data then you'll know about Anscombe's quartet - a set of four different datasets, each with the same mean, variance and correlation's often used to emphasise the importance of visualsing data...Over 40 years later, this still applies and it got me thinking about visual representations in maps, and whether there is a spatial equivalent to Anscombe's quartet. I'm not sure there is but I think the topic of choropleth classification forms a kind of opposite case...

  • The PolicyViz Podcast Episode #27: Dear Data Wrap-Up
    For the final episode in 2015, I’m excited to welcome Giorgia Lupi and Stefanie Posavec back to the show to talk about their year of Dear Data, their analog data visualization project. Our conversation is a bit broader than just about the Dear Data project. I was curious about their reflections on whether the project changed their creative process and their perceptions of the data visualization field. Giorgia and Stefanie also make a special announcement at the end of the episode...
  • 3 Powerful Lessons I have learnt As An Information Designer
    Designing information effectively is a wonderful and complex challenge. I feel grateful that in the past ten years I have had the opportunity of working with extraordinary teams of scientists to the end of communicating complex data. These three lessons are among the most precious lessons I have learnt along my journey...
  • Build Fantastic Visual SVG Widgets
    Svidget.js is a JavaScript framework for creating immersive and fully interactive SVG widgets...Currently with data visualization on the web, you have two options. Go with a high level charting library, which in many cases have their own limitations, making customization difficult or impossible. The other option is go with a low level visualization library like D3, which comes with a steep learning curve and a time cost to implement...Svidget bridges the gap between those two options by allowing you to express your visualizations as simplistic or as specialized as your application requires.

  • Heatmap With 2D Kernel Density Estimation Of Force Layout
    A heatmap of node positions over the course of a force-directed layout algorithm, using 2D kernel density estimation (KDE) with the Gaussian kernel to determine heatmap values. Compare with a heatmap that does not use KDE. This network is the mobile patent suit data....
  • Particle Edges Dendrogram
    Particle edges from d3_glyphEdges are the most difficult edge type to implement. Here's an example using a dendrogram and the connecting paths from the dendrogram...

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

Wishing you the best,
