A scatter plot shows NHL playoff performance across teams and years, plotting each team-season as a colored circle based on goals scored against year, with team membership encoded by color. The visualization includes axes, labels, and an interactive color legend that highlights points from a selected team when hovered. Built with D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.csvParse` to load and map the dataset, while custom modules manage axes and legend rendering. Data comes from a CSV of NHL playoff records.
