A scatter plot of the Iris dataset lets users explore relationships between flower measurements through interactive dropdown menus that select which attribute appears on each axis. The visualization renders 150 circles as SVG elements using React components, with scales created via `d3.scaleLinear` and axes built from `xScale.ticks()`. Users switch between sepal and petal dimensions or species via a React Dropdown component, while D3's `csv` loads the remote dataset and `format` handles tick labels.
