Exploring New Technologies for Making Maps (Part Two): Two Fragment Shaders and a Mouse
In part one of this series we started learning how to make maps rendered by WebGL, a browser based hardware-accelerated graphics API for 2D and 3D graphics. Our access to this technology was via Tangram, a map rendering library from Mapzen. This post will focus primarily on shaders, those perplexing parallel programs that power our […]

Smoothly animate thousands of points with HTML5 Canvas and D3
Sometimes in life, you’ve just gotta move thousands of points around on the screen. For hundreds of points, this can be accomplished with D3 through d3-transition on SVG nodes, but this typically becomes too slow when you need to animate more than a thousand points. So how do you do it? Enter canvas. Each point […]

Visualizing the Health of the Internet with Measurement Lab
How do you visualize the “Health of the Internet”? This was the challenge posed to the Data Vis team at Bocoup by our client Measurement Lab, a nonprofit that collects millions of Internet speed tests every month from around the world since 2009. This data is invaluable to policy makers, researchers, and the general public […]

Exploring New Technologies for Making Maps. Vector Tiles & WebGL (Part One)
Maps are both practical and political. They possess undoubtable utility for navigating the physical world and have a long history of being used to shape and reshape the our social and political conceptions of the world. The ability to mark a territory, carve up a continent (or remember one), count a people, or map our […]

We’ve been thinking a lot about those very questions, especially in the coming crescendo of election […]

Showing Missing Data in Line Charts
While working on visualizing the results of internet speed test data for Measurement Lab, it became clear that there wouldn’t always be data for every geographic location on every single day. We might go several days without meeting a minimum threshold of tests, meaning there would be gaps in our data. This is a pretty […]

Improving D3 Path Animation
D3 provides us with many of the basic building blocks needed to make charts in browsers while also making it extremely easy to animate them. One of the most common charts created with D3 is a line chart, often consisting of a series of SVG <path> elements to visualize the data. In this post, I […]

Building a Better Lyra
Last year we had a successful Knight Foundation Prototype Grant-funded collaboration with the University of Washington Interactive Data Lab (IDL) to improve their Voyager data exploration tool. At the end of our collaboration we knew we wanted to work with the amazing team from the IDL again, so we were thrilled when Jeff Heer & […]
