# Observable Plot   The JavaScript library for exploratory data visualization

Create expressive charts with concise code

## 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.
