Struct ChartRenderer 

pub struct ChartRenderer { /* private fields */ }

Turns a chart’s option and layout into a display list.

The renderer is the only place that knows how a chart is put together: the background, the grid, the axes, the series, the title, and the legend. It writes into a display list, which the backends replay — so a new backend never has to know what a chart looks like.

The renderer is public so that a benchmark — or a server-side render — can measure the cost of a layout without a canvas.
