This scatterplot uses leaf-shaped SVG symbols to compare the distribution of maple and oak observations across two numeric coordinates. The visualization loads external maple and oak illustration SVGs from an Amazon S3 bucket, converts them into reusable patterns via `d3.xml`, and applies them as fill patterns using D3 v5’s selection and scale APIs. Points are plotted with the `d3.symbolSquare` marker, while axes and titles are generated through `d3.axisBottom`, `d3.axisLeft`, and a custom text element. The chart’s data consists of nine labeled coordinate pairs representing the two tree species.
