This scatter plot visualizes the relationship between the length and width of objects, using symbols to distinguish materials. The axes are labeled Length and Width, and a legend identifies the material categories. Built with Observable-style code using D3 v7, it loads data from a CSV file hosted in a GitHub gist. The visualization employs `d3.scaleLinear` for the axes, `d3.scaleOrdinal` with `symbolsFill` for shape encoding, and custom modules for rendering axes and the shape legend.
