Compiles Vega-Lite 6.5 to Vega 6.4 and renders to SVG with the string renderer (no canvas); PNG comes from the Chrome canvas. Both libraries run from node_modules inside a sandboxed Chrome renderer with network blocked, so Vega expressions never run in the API process. Data must be inline: any url is rejected and loader access is blocked and reported. Returns size, mark item count and warnings.
