Info
API

Import#

import { CngxChartRenderer } from '@cngx/common/chart'

Description#

A rendering backend for <cngx-chart>. Both backends compose against the same LayerGeometry surface the layer atoms publish, so a single chart-authoring API drives either one with no consumer change.

The SVG backend is a passthrough (layer atoms self-render); the Canvas backend paints the geometries onto a <canvas> 2D context.
