This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis against sepal length on the y-axis. Each flower is drawn as a circle using D3 v7’s `select`, `append`, and `join` APIs, with scales created via `scaleLinear` and `extent`. The chart includes axis labels and scales, rendered as SVG. The plot uses d3’s `csv` loader to fetch remote data and includes axes from `axisBottom` and `axisLeft`.
