This example visualizes the Iris dataset by plotting sepal length against sepal width as a scatter plot, revealing the distribution of measurements across the flower species. It loads the data from a CSV file using D3’s `d3.csv` method, then parses the numeric fields with unary plus operators. The visualization uses D3 v6’s `scaleLinear` for both axes and renders circles via SVG, with axis labels added through `d3.axisBottom` and `d3.axisLeft`. The chart’s dimensions are set with explicit margins, and the drawing area is translated accordingly within the SVG container.
