Each image links to the example file that draws it. The example index names the function and the command for every image. All data is synthetic; the images are actual native renderer output. GIFs show exported animation frames.

Pearl · Terrain · Contours · Box plot

Lines · Error bars · Histograms

Bars · Donut · Animated curves

Radar · Radar with value labels · Polar · Compass rose

Wind field · Surface currents · Colour-mapped points · Bubble chart

Forecast bands · Step schedule · Twin axes · Small multiples

Draw styles: Precise · Sketch (hand-drawn) · Milkyway · Constellation

Milkyway uses line-only series; Constellation places stars at the source samples.

Six editable visual recipes show how palettes, axes, materials and labels restyle charts built with the same APIs.

Chart types

Chart	Input	Guide
Lines and scatter	f64 columns through ColumnSource	Usage · Series schema
Area fills and step lines	A line's fill (to a baseline or another series) and interpolation	Area fill and step lines · area_step.rs
Error bars	X, Y and error columns	error_bars.rs
Histograms	Bin edges and counts	Histograms
Heatmaps and contours	X and Y coordinate columns and one z column per grid row or column (MatrixRef)	heatmap_contours.rs
Vector fields (quiver)	Anchors and (u, v) columns, or two matrices on a grid	Vector fields · vector_field.rs
Colour and size maps (bubbles)	A value column per point, mapped by PointColorMap through the colorbar (Config.colorbar) or by PointSizeMap through its size domain	Point colour and size maps · value_maps.rs

Every row above pies and donuts is a column-backed chart: its data enters through ColumnSource into one GPU column pool, and these charts share one renderer, picking and export path. Overlay axes and subplots work with these charts, except that a polar chart takes no overlay axes. Streamed, non-resident sources draw lines, scatter, error bars, histograms and heatmaps in a single-panel document. Contours, fills and step lines, vector fields, colour and size maps, polar plots, and documents with overlays or subplots reject streamed sources with an explicit error. Pies and donuts, categorical bars, box plots and radar charts keep their categories and values in their own small model, with no ColumnSource, and each has its own renderer. The annotation layer works on both kinds.

Quick start

Use Rust 1.99 or later and a working GPU driver. The repository pins Rust 1.99.0. Add these dependencies to your application's Cargo.toml:

[dependencies]
renderer = { package = "figgy-renderer", version = "0.18.1" }
wgpu = "30"
pollster = "1"

The version line installs figgy-renderer 0.18.1, with figgy-model 0.12.1, from crates.io. With a local checkout, use path = "../figgy/crates/renderer" (relative to your application) instead of version. Code written for 0.17.0 needs the changes in the migration notes.

Copy this into src/main.rs, then run cargo run. It writes line.png without opening a window. renderer is the Rust import name of the figgy-renderer package.
