Data Visualization and D3.js Newsletter Issue 26 Weekly Data Visualization and D3.js Newsletter

Hi Friends -

Welcome to the twenty-sixth issue of's Weekly Newsletter .

Onwards to this week's links...


  • Data Visualization for the Color Blind
    Color blindness is a color vision deficiency which affects roughly 8% of the North American male population and 0.5% of the female population. So when designing data visualizations and dashboards, it’s important to keep this group of people in mind to make sure they are seeing the same results as everyone else.
  • Binify + D3 = Gorgeous Honeycomb Maps
    Most Americans prefer to huddle together around urban areas, which raises all sorts of problems for map-based visualizations. ... Kevin Schaul released an exciting new command-line tool called binify that offers a brilliant alternative ... I put together this tutorial to demonstrate how you can take a raw series of coordinates and end up with a binned hexagonal map rendered in the browser using D3.js and ToppoJSON.

Data Visualization Reading and Videos

  • Fundamentals of Data: Visualization for iOS
    Video - Personal Capital's engineering team hosts a Meetup at company headquarters in Redwood City, California. The topic: Fundamentals of Data and Visualization for iOS
  • What Type of Visualisation Should You Use to Tell Your Data-Driven Story?
    The range of data visualisation tools is growing quickly, making choosing which one to use and which style to opt for even trickier. ... Remember that you don’t always need a visualisation to tell a data-driven story: sometimes words do it best. Otherwise, only select and visualise the key data that tells the story.
  • Visualizing the Connectome
    Last year, I blogged about a new and very pretty way of displaying the data about the human ‘connectome’ – the wiring between different parts of the brain. But there are many beautiful ways of visualizing the brain’s connections, as neuroscientists Daniel Margulies and colleagues of Leipzig discuss in a colourful paper showcasing these techniques.

D3.js Reading and Videos

  • Venn Diagrams with D3.js
    A couple of my goals for this year are to learn both Javascript and D3.js. ... To get started with this, I thought I'd try use D3 to create the simplest possible visualization I could think of - the Venn diagram.
  • TopoJSON Release 1.1.0
    The topojson command now uses a hashtable rather than a sparse array to compute the topology. This eliminates most out-of-memory errors and offers dramatically better performance with large inputs, such as zipcode tabulation areas and census blocks. ... and more!
  • D3.js GeoJSON in Leaflet.js
    A simple test of extending the L.TileLayer to fetch geoJSON tiles from openstreetmap and render them with D3.js.
  • Over 1000 D3.js Examples and Demos
    One of the best things that I like about D3 is the ridiculous amount of awesome demos available online and last night I have stumbled on an excel sheet with 1,134 examples of data visualizations with D3.
    [Editor's Note - spreadsheet mentioned is D3.js Gallery Data from @d3visualization]

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

Wishing you the best,
