Enum BackendKind 

pub enum BackendKind {
    WebGpu,
    WebGl2,
    Canvas2D,
}

The rendering backend a chart is running on.

The backend is chosen at run time: the chart asks for WebGPU, falls back to WebGL2, and falls back again to Canvas2D. From the outside the three look identical, because they all replay the same display list.

Variants

WebGpu

WebGPU: the fastest backend, and the one the chart prefers.

Vector geometry is tessellated into triangle batches and uploaded to the GPU once; a steady-state frame issues a handful of draw calls and touches no JavaScript.

WebGl2

WebGL2: the GPU fallback for browsers without WebGPU.

The same batches as WebGPU, drawn through WebGL2 instancing.

Canvas2D

Canvas2D: the universal fallback.

The display list is replayed as immediate-mode canvas calls. Slower than the GPU backends, but it works everywhere.
