{"version":"1.0","type":"rich","title":"Attention map","description":"This attention map visualizes eye-tracking fixation data from multiple users viewing city images, using a density-based contour overlay to highlight areas of visual focus. The D3.js visualization, built with the `d3-contour.v1` plugin, renders a heatmap-like SVG gradient alongside the mapped fixation points from the data set. The color scale, based on `d3.interpolateInferno`, encodes the density of fixations across each image, revealing where observers concentrated their gaze. The implementation uses raw CSV data containing fixation coordinates and durations to generate these contour layers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8e70a89307454c8e96408b2c96c8f908?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
