Scan Path
This visualization shows a scan path of eye-tracking fixations overlaid on a map of Antwerp, with circles representing fixation points and their sizes scaled by fixation duration. The red line connects successive fixations in temporal order, revealing the viewer’s viewing sequence across the image. Using D3 v5, the code loads CSV data, maps fixation coordinates through `scaleLinear` and `extent`, and renders SVG circles and a path via the `line()` generator. Fixation durations set circle radii, while the background image comes from an external URL specified in the stylesheet.
