This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width, with points colored by species (setosa, versicolor, and virginica). Built with D3 v6, it loads CSV data and renders SVG circles, using `scaleLinear` for axes and `axisLeft`/`axisBottom` for ticks. The code maps `petal_length` to the x-axis and `petal_width` to the y-axis within a full-screen SVG, with fixed margins and a default radius of 5 pixels.
