{"version":"1.0","type":"rich","title":"This is a heatmap","description":"This heatmap overlays eye-tracking fixation points on a static map of Antwerp’s metro system, with each point’s position derived from `MappedFixationPointX` and `MappedFixationPointY` coordinates in `data.csv`. Using React and D3’s `scaleLinear` for coordinate mapping, the visualization renders an SVG containing the fixation data. The background image is applied via CSS, while the SVG is sized at 960×500 pixels. The code loads CSV data asynchronously with `d3.csv`, converting numeric fields before passing them to the render function, though no explicit heatmap aggregation or density calculation is visible in the provided source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2fa2a2fc74024497b1f173d890ff64f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
