A scatter plot of Iris flower measurements shows sepal length against sepal width, with each point colored by species origin. The plot includes labeled axes, gridlines, and a title. Built with D3 v6, the visualization uses `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleOrdinal` to map categorical species values to colors. Data is loaded as CSV from the uiuc-cse GitHub repository and rendered as SVG circles with fixed radius and opacity.
