This scatterplot displays the relationship between sepal length and petal length for three iris species, with each species represented by a distinct color. The visualization uses D3.js v4 to render SVG circles, positioning them based on data from a remote CSV file. The code employs `d3.scaleLinear` for both axes, `d3.scaleOrdinal` for categorical color mapping, and `d3.axisBottom` and `d3.axisLeft` for tick marks. A legend identifies the species by color.
