The visualization displays eye-tracking scan paths over a map of Antwerp’s metro system, with each participant’s fixations drawn as colored circles and connected by sequential lines. Circle size encodes fixation duration, while color identifies the user, and hovering reveals exact duration and participant details. Built with D3 v5, it uses `scaleLinear` for the x/y axes, `scaleOrdinal` with `schemeCategory10` for colors, and `nest` to group data by user, rendering paths and circles as SVG elements on a styled background.
