This interactive scatter plot shows the relationships between iris flower measurements, with each data point rendered as a distinct symbol based on species. Built as a reusable D3 module, the visualization uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` with `d3.symbols` to map categorical species to different glyphs, and `d3.axisLeft` and `d3.axisBottom` for labeled axes. The code loads the Iris dataset from a GitHub gist via `d3.csv`, parses numeric columns, and dynamically sizes the SVG to the browser window, demonstrating a flexible symbol-based scatter plot template.
