AN SVG IS ALL YOU NEED

Summary from the TLDR newsletter

SVGs are vector graphics in a simple XML format. They are supported on almost every device and platform. With embeddable scripts to make them interactive, SVGs are way more capable than many people realize. It is entirely feasible to implement an entire data analysis pipeline in an SVG. A completely self-contained SVG file can fetch data from a versioned repository, process that data, and generate visualizations without any server-side magic required.
