This scatter plot visualizes the Iris Dataset, a classic multivariate dataset of flower measurements, using a vanilla HTML implementation with D3. It displays the data points across multiple dimensions, allowing comparison of sepal and petal lengths and widths across the three iris species. The visualization leverages `d3.scalePoint` and `d3.scaleLinear` to map the axes, with `d3.select` and `d3.axisBottom`/`d3.axisLeft` rendering the chart elements. The plot is interactive, highlighting individual points on hover to reveal their species and values.
