Upgrading d3 from v3 to v4

July 31, 2016

We recently upgraded to d3js  v4.1.0. Here is what we did to fix the breaking changes:

After the upgrade our data visualizations stopped being generated, and on a closer look we were getting this js error in Chrome:

Uncaught TypeError: Cannot read property 'format' of undefined

It turns out  d3js  v4.1.0 is a major rewrite with several breaking changes, so be prepared to spend half a day looking at it. Fortunately the d3.js documentation is very comprehensive, including the documented changes  - which is a must read.

Here are the Firefox errors we fixed to get it working again:

TypeError: d3.time is undefined

  • fix: d3.time.format => d3.timeFormat
  • fix: d3.time.scale => d3.scaleTime
  • fix: d3.time.months => d3.timeMonths

  • fix: d3.time.days => d3.timeDays
