D3 based reusable chart library for data visualization

naver.github.io/billboard.js ↗

billboard.js is adding a canvas renderer — an SVG chart library admitting SVG has a ceiling.

chartingcanvas-renderingtree-shakingpre-release-trainrendering-parity
◆Current state
The library is mid-flight on a 4.0.0 pre-release train, and the defining addition is a canvas rendering mode alongside the existing SVG output. The same first candidate made grid, regions and category modules tree-shakable, added file extensions to type declarations, and exported shape option types from the main entry. Everything published since has been canvas follow-up: background image positioning, rendering and touch-interaction parity, candlestick labels aligned to wick endpoints.
◆Where it's heading
Two constraints are being addressed at once. Canvas is the answer to dataset sizes where per-point DOM nodes stop being viable, and the fact that three consecutive candidates are spent on parity fixes shows how much behaviour an SVG-native library has to re-implement to make the alternative renderer feel identical. Tree-shakable modules attack the other constraint — bundle weight — which matters to exactly the same teams choosing a chart library on performance grounds.
◆Prediction
Expect further candidates before 4.0.0 stable, still weighted toward canvas parity in interaction and label placement, since that is where every candidate so far has landed.

◆Recent moves

  1. 1mo ago

    Candlestick label alignment and table-view number formatting

    Candlestick labels aligned with wick endpoints in canvas mode, plus a numberFormat option for the table-view plugin. More canvas parity work, which is what every candidate after the renderer landed has consisted of.

    Canvas background position and touch-interaction parity fixes

    Background image positioning corrected in canvas and rendering aligned with touch interaction behaviour. The parity tax of running a second renderer, paid one candidate at a time.

    Canvas render review fixes

    A single fix addressing issues raised in canvas render review, published hours after the renderer itself. Immediate cleanup rather than new capability.

    Canvas rendering mode and tree-shakable ESM modules

    ⚡ SPARK

    The candidate that sets the 4.0.0 agenda: a canvas rendering mode beside SVG, and grid, regions and category modules made tree-shakable. The three candidates that follow are entirely consequences of this one.

    Sanitization function update on the 3.18 line

    A lone pre-release on the previous line whose only change updates the sanitization utility. The five-month gap before the 4.0.0 train suggests development had already shifted to the major.
