This example displays a principal component analysis (PCA) scatter plot of radio-related entities, plotting each point on two axes with a red, semi-transparent circle. The visualization supports interactive zooming and panning through a `d3.zoom` behavior, and includes a toggle to reveal or hide the corresponding name labels for each data point. The SVG visualization uses `d3.scaleLinear` for axis scaling and `d3.axisBottom`/`d3.axisLeft` for grid lines, with data loaded from a remote CSV file using `d3.csv`.
