{"version":"1.0","type":"rich","title":"Scan Path","description":"This visualization displays a scan path of eye-tracking fixations over a metro map of Antwerp, with a red line connecting fixation points and red circles marking each location. It combines two views: the raw scan path overlaid on the background image and a density contour layer rendered via `d3.contourDensity` with a sequential green color scale (`d3.scaleSequential(d3.interpolateGreens)`). The code loads data from a CSV file using `d3.csv`, scales coordinates with `d3.scaleLinear`, and draws paths using `d3.geoPath`. Fixation points are mapped to SVG coordinates, with contours computed from the same data points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6dafe196f969411ca6c7538cd3e43699?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
