The article describes how to create simple SVG sparklines—small, axis-less line graphs—using the SVG polyline element, which takes a list of x,y coordinate pairs. It highlights the ease of generating them programmatically and hints at a small problem to spot in the example code.
A proposed standard for embedding spritesheet metadata (such as layout and animation sequences) directly inside a PNG file using a custom chunk, eliminating the need for separate JSON or XML files. The page includes the specification details and an online tool for inlining metadata into PNG spritesheets.
The article explains how to create simple, lightweight sparkline charts using inline SVG, demonstrating a straightforward technique for embedding data visualizations directly in HTML without JavaScript or external libraries.
