Hi Friends -
Onwards to this week's links...
Welcome to issue 96 of the DashingD3js.com Weekly Newsletter
- Bézier Clock
The program (made with Processing.js) is very simple; it just linearly interpolates five Bézier control points between pre-defined states...By adjust the locations and distance of the control points from the node points, you can create complex curves with very few points. What this program does is calculate straight-line paths between each point's location on the current and next shown digit, and draws a Bézier curve through the interpolated points.
Data Visualization Reading and Videos
- Dominikus Baur: Web-based Data Visualization On Mobile Devices - JSConfEU 2014
In this talk, I will present a quick run-through of all the relevant aspects of mobile web-based datavis: * What graphics technology (Canvas, SVG, WebGL) to choose? * How to include all the neat HTML5-supported sensors to do cool stuff (GPS, device orientation)? * What amazing things can be done with multi-touch input? * What changes for information and chart design? * How to best debug mobile visualizations?
- The Human Body, According To Venture Capitalists
The investors who support emerging medical technologies play an important role in determining which new therapies reach the public. A Wall Street Journal analysis of venture investment trends since 1999 reveals which body systems stand to benefit most from their decisions. The charts below show venture-capital financing in both the amount invested and number of deals for various body parts.
- The Easiest Way To Make Bullet Charts In Excel
There are lots of ways to make bullet charts, some easier than others, some better suited for specific visualization contexts. Hell, there are plug-ins you can purchase that make it a snap. Except when my plug-in broke and I had to remake about a bazillion bullet graphs in several dashboards. :/ doesn’t even begin to express it. So yeah, we could use yet another method. This is the easiest way I have found to do it right inside Excel.
- How We (Interactive Things) Create Color Scales
This article is about creating refined color scales for charts and visualizations. You will get insights from, and a deeper view into, our working process at Interactive Things.
For us, a diverse and balanced palette is one of the key components to efficiently communicate information trough color. A list of the used tools can be found at the end of this article.
- 100 Years Of Data Visualization Best Practice
Willard C Brinton wrote the first book on data visualisation best practise. When? 100yrs ago. Brinton should be celebrated alongside other visualisation pioneers such as Playfair, Priestley, Tufte and Bertin. This tumblr is by Andy Cotgreave (@acotgreave). Follow the conversation on Twitter with #100yrsOfBrinton. The complete book is available to read on archive.org.

- D3.js Step By Step - A Series Of Posts To Get You Started
This series explores some key concepts in D3.js by building up an example, step by step, from a bare-bones pie chart to an interactive, animated donut chart that loads external data...here's a breakdown of the steps we'll be covering: Intro, A Basic Pie Chart, A Basic Donut Chart, Adding a Legend, Loading External Data, Adding Tooltips, and Animating Interactivity...
- d3.format Tester
This little tool helps you try out d3.format specifiers on different numbers. Documentation for format specifiers is here....
- Building A D3 Plugin
Some awkward, common visualization constructs lend themselves to a plugin form, a reusable DOM-stamper that can be applied to an ‘svg’ or ‘div’ tag, with a few parameters and maybe some data. For example take a colorbar or legend-box, often unglamorous visual indicators which are tedious to repeat from scratch...What follows is my current state of play, with inspiration from Mike Bostock’s article on reusable charts among others.
