  • 10 Significant Visualisation Developments: January To June 2016
    To mark each mid-year and end of year milestone I try to take a reflective glance over the previous 6 months period in the data visualisation field and compile a collection of some of the most significant developments. These are the main projects, events, new sites, trends, personalities and general observations that have struck me as being important to help further the development of this field...
  • Map Scroller Associated With Video Position
    Play the video once loaded to see the example...I created the path with the help of Geojson.io, and it's not exact. The idea was showing the possibility of syncing the video with the path...The video is a time lapse (I don't dare driving this fast) taken at the paradise valley close to Agadir, Morocco. Go there if you have the opportunity!...

  • The Sieve of Eratosthenes
    A prime number is any positive integer that is only divisible by one and itself. Primes are very important across disciplines and especially in encryption and computer science. One of the reasons primes are so important is because it is very difficult to easily determine whether a number is prime or not. Moreover, what happens when you want to find, say, all the prime numbers below some N, say, 100?...
  • The PolicyViz Podcast Episode #55: William Cleveland
    I’m very excited to have William Cleveland join me on the show this week. You’ve probably heard of some paper by “Cleveland and McGill”–yes, that Cleveland joins me on the show this week. We talk about his seminal research, his recent work on big data, intensive computational techniques, and more...
  • Why Sightline?
    Sightline is an automatic data visualization collection and discovery service that leverages the rich visualization ecosystem of the internet and puts it in one place...
  • How-To: United States of Craigslist, Chalkboard Map
    Ah the trusty old, well-worn, United States of [Thiessen Polygon] Map. But at least I was a relatively early adopter (the original version was made in…yikes!…2011). Sure, this post will show you how to make these boundaries, but more interestingly, it will show you how to make a chalkboard-style map!...
 

D3.js Reading and Videos
 

  • On D3 and Arrow Functions
    D3 implements a useful pattern where functions that operate on selections are given the selected DOM element via this. It allows us to use the selection’s bound data and the DOM element within the same context...When making the switch to ES6, it seems reasonable that we’d want to use the syntactically delectable arrow functions to replace all our callback functions...However, arrow functions have an additional feature that prevents D3 from passing us a custom this and so our code breaks or leads to the wrong behavior...
  • reusable-d3-charts
    Reusable charts built with D3. Built on Web standards, fully customizable...
  • Moon Calendar
    A 2016 moon calendar. Click to show today. Uses the "Simple" moon phase calculation from Moon Phase Calculators...
  • Degrees Of Separation On A Tree Algorithm
    Imagine that you are like me and looking for an algorithm to compute degrees of separation along a hierarchical tree like the ones pictured below. Your tree could represent any data — let’s pretend it’s a company org chart with node A as the CEO, nodes B and I are execs, and so on. The distance, or degrees of separation, between any two nodes is the number of links along the shortest path that separates them...

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

Wishing you the best,
