This scatter plot displays the relationship between sepal length and petal length for the three Iris flower species, with each species represented by a distinct symbol shape from D3’s `symbolsFill`. The visualization uses `d3.scaleLinear` for the axes, `d3.scaleOrdinal` to map species to shapes, and `d3.symbol` to generate the marks, with data loaded from a local CSV file via `d3.csvParse`. A custom legend, built with D3’s join pattern, identifies the shape-to-species mapping, while axes are rendered using `d3.axisLeft` and `d3.axisBottom`.
