This example displays the classic Iris dataset using a scatter plot to visualize the relationship between petal length and petal width, with each of the three species color-coded (skyblue, lightgreen, orange). The visualization loads CSV data directly from a GitHub repository using d3.csv, maps the data to screen coordinates with d3.scaleLinear, and renders circular markers as SVG elements. Axis labels are added for both dimensions, and the layout adapts to the full browser window size. The code relies on D3 version 6.7.0 for data parsing, scales, and SVG generation.
