{"version":"1.0","type":"rich","title":"Heat?","description":"This visualization uses fixation data from the Old Faithful dataset to show the density of eye-tracking points on a stimulus image. The contour map, generated with `d3.contourDensity` and rendered via `d3.geoPath`, uses a sequential green color scale to represent point concentration. The code loads a CSV of mapped fixation coordinates, scales them linearly, and applies a bandwidth of 50 to create smooth density regions. The SVG output highlights areas of high visual attention based on recorded user gaze patterns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bb0ab570b004ea499d2941fc3ce87f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
