This scatter plot visualizes a synthetic IRIS dataset, categorizing each point by one of three categories using distinct colors (skyblue, lightgreen, orange). D3's `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` APIs map the feature1 and feature2 values to the SVG canvas. The plot is generated from a local CSV file, and the code uses D3's `csv` data loader to parse the data before rendering the circles.
