A scatter plot visualizes the Iris dataset, showing how flower measurements relate based on user-selected axes. The chart displays species as colored dots, with orange, teal, and purple representing the three Iris varieties. Interactive dropdown menus let viewers choose which measurement appears on the x and y axes. This React application uses D3 v7 scales (scaleLinear and scaleOrdinal) to map data values to coordinates and colors, rendering SVG circles for each observation while supporting dynamic axis and label updates.
