This example demonstrates how to render a line chart directly onto a canvas element using D3’s `d3.line` generator with a custom rendering context. A simple dataset of five coordinate pairs is drawn as a single path, with the line generator’s `context` method set to the canvas’s 2D drawing context. The code explicitly manages the canvas stroke styling and path initialization, bypassing SVG entirely. It relies on D3 v7 and the native Canvas API’s `getContext('2d')` and `stroke()` methods to produce the final output.
