This visualization displays the classic Iris dataset as a scatter plot, mapping sepal length on the x-axis against petal length on the y-axis, with each species distinguished by a unique symbol shape. The chart includes labeled axes and a shape legend identifying the three species. Built with d3.v7, the code uses `scaleLinear`, `scaleOrdinal`, `symbolsFill`, and `symbol` to position and render marks, while `axisLeft` and `axisBottom` generate the axes. Data loads from a remote CSV via `fetch` and `csvParse`.
