This interactive scatter plot compares sepal length and width across Iris species, with filters for selecting numeric columns and a categorical color dimension. It loads CSV data via the `d3.csv` API and maps columns to user-chosen fields. The visualization uses SVG rendering with D3 v7, featuring axes via `d3.axisBottom` and `d3.axisLeft`, ordinal color scaling, and hover tooltips. Users can also render a legend and resize the chart through a ResizeObserver.
