Iris Scatter Plot
This scatter plot visualizes the Iris dataset, showing sepal length against sepal width for three species of iris flowers. The data comes from a CSV file containing measurements of 150 samples, with each species represented by a different color using D3’s scaleOrdinal and schemeSet1 palette. The visualization uses D3 v5 to load the data via csv(), create linear scales with scaleLinear, and render SVG circles with axisBottom and axisLeft for labeled axes. The chart includes gridlines and a title, with opacity applied to circles to reveal overlapping points.
