This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis against petal length on the y-axis. Each flower is represented by a circle, colored by its species (setosa, versicolor, or virginica) using a custom color scale. The visualization is built with D3 v7, using the `scaleLinear` for axes, `scaleOrdinal` for color mapping, and a `scatterPlot` module that adds axis labels and legends. Data is loaded from a CSV file and rendered in an SVG canvas.
