canvg is a JavaScript graphics library and rendering engine designed to parse SVG vector data and draw the resulting graphics onto HTML5 canvas elements. It functions as a pipeline that transforms structured vector markup into pixel-based output for use in web browsers. The library provides a framework for web vector graphics animation, executing rendering cycles to maintain consistent visual motion. It also enables interactive vector graphics by mapping user input, such as mouse clicks and touch events, to specific shapes within the rendered canvas. The engine handles vector-to-pixel transf

Perfmap is a web performance visualization tool and frontend resource loading analyzer. It functions as a diagnostic tool that identifies slow-loading assets by highlighting their completion time and download duration directly in the browser.
