Scatter
A scatterplot displays eye-tracking fixation points over a map of Antwerp, with each red dot representing a fixation location from participant data. The visualization uses an SVG rendering approach where D3 v5’s `csv` loads the dataset, and `scaleLinear` with `extent` maps the mapped fixation X and Y coordinates to screen positions. Circles are appended via `selectAll`, with a fixed radius of 10 and 0.1 opacity, revealing clusters of visual attention across the image.
