Overview

Each chart type is a combination of marks, scales, coordinates and transforms (see Concepts). The pages of the gallery show an example of each:

Cartesian charts: bars, lines, areas, scatter plots, bubbles, reference lines, annotations, lollipops, dumbbells, combo charts, two y axes, population pyramids, slope charts, error bars and Gantt charts.
Radial charts: pies, donuts, polar areas, radial bars, radar charts and gauges.
Hierarchical charts: packed circles, treemaps, sunbursts, icicles, tree diagrams and dendrograms.
Statistical charts: histograms, box plots, density plots, violin plots, ridgeline plots, hexbin plots, density contours, parallel coordinates, trend lines, moving averages, heatmaps, waterfalls, funnels, candlesticks, bullet charts, calendar heatmaps, Marimekko charts and sparklines.
Small multiples: grids of charts that share their scales, one per facet.
Flows: Sankey diagrams and chord diagrams.
Networks: network graphs with a force-directed layout.
Maps: choropleths and points on maps, from GeoJSON.

The examples chart records like these:

public sealed record Sale(string Region, int Year, double Amount);

public sealed record Reading(DateOnly Date, string City, double Temperature);

public sealed record Share(string Name, double Value);

When an example uses SampleData, it is a list of such rows: SampleData.Sales has the sales of four regions over three years, and SampleData.Readings the monthly temperatures of three cities in 2024.
