What is Plot?

Examples

Marks

Plot doesn’t have chart types. Instead, it has layered geometric shapes such as bars, dots, and lines.

Scales

Scales map an abstract value such as time or temperature to a visual value such as position or color.

Transforms

Derive data on-the-fly while plotting, say to bin quantitative values or compute a rolling average.

Facets

Small multiples facilitate comparison by repeating a plot across partitions of data.

Projections

Plot supports GeoJSON and D3’s spherical projection system for geographic maps.

Built with D3

Plot is built by the same team as D3. If you know some D3, you’ll be right at home with Plot.
