Also, Relay is built by Puppet, so not a separate company :)

We're fans of Invision + elements of material design. Some inspiration there for sure.

Thanks. We're just getting started!

We do use D3 under the hood.

We're going to darken the text on our next push. Thanks for pointing it out.

We'll make an adjustment. Thanks for the feedback.

FYI, your Contrast Ratio is 2.8:1. Aim for 4.5:1

Try using #4c4c4c

You can use this tool to test. http://webaim.org/resources/contrastchecker/

A bad contrast ratio will always look very bad on older screen, making text hard to read. It is also hard to read by people with eyes issues.

"WCAG 2.0 level AA requires a contrast ratio of 4.5:1 for normal text and 3:1 for large text (14 point and bold or larger, or 18 point or larger). Level AAA requires a contrast ratio of 7:1 for normal text and 4.5:1 for large text."

Nice! What did you guys use to build the visualizations?

Some of them are created using After Effects, HTML/CSS and iOS code. Was this your question?

Nice to see the spread on multiple Iaas.

Great place. Great people.
