{"version":"1.0","type":"rich","title":"size by column sum","description":"This visualization shows the cumulative sum of a numerical attribute over time, with point markers growing in size as their aggregated value exceeds thresholds of 10 and 100. The map uses CartoCSS and Torque’s frame-based animation to render 128 time steps, applying a sum aggregation function to the `whatever_column`. Marker width scales from 4 to 14 pixels, and trailing frames become larger and more transparent, creating a motion trail effect. The data comes from a gist by andrewxhill, with styling defined directly in the `cartocss.css` file.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-48aebf8193c0b5066a3b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
