Changes in D3 7.0

Released June 11, 2021.

This document covers only major changes. For minor and patch changes, please see the release notes.

D3 now ships as pure ES modules and requires Node.js 12 or higher. For more, please read Sindre Sorhus’s FAQ.

d3.bin now ignores nulls. d3.ascending and d3.descending no longer consider null comparable.

Ordinal scales now use InternMap for domains; domain values are now uniqued by coercing to a primitive value via object.valueOf instead of coercing to a string via object.toString.

Array-likes (e.g., a live NodeList such as element.childNodes) are converted to arrays in d3.selectAll and selection.selectAll.

Changes in D3 6.0

Released August 26, 2020.

D3 now uses native collections (Map and Set) and accepts iterables. d3.group and d3.rollup are powerful new aggregation functions that replace d3.nest and work great with d3-hierarchy and d3-selection. There are lots of new helpers in d3-array, too, such as d3.greatest, d3.quickselect, and d3.fsum.

D3 now passes events directly to listeners, replacing the d3.event global and bringing D3 inline with vanilla JavaScript and most other frameworks.

d3-delaunay (based on Vladimir Agafonkin’s excellent Delaunator) replaces d3-voronoi, offering dramatic improvements to performance, robustness, and search. And there’s a new d3-geo-voronoi for spherical (geographical) data! d3-random is greatly expanded and includes a fast linear congruential generator for seeded randomness. d3-chord has new layouts for directed and transposed chord diagrams. d3-scale adds a new radial scale type.

… and a variety of other small enhancements. More than 450 examples have been updated to D3 6.0!
