{"version":"1.0","type":"rich","title":"[DataVizStudy]Using Size with Points on the map","description":"This interactive world map displays global terrorism events from 2018, using the [2018 Global Terrorism Database](https://gist.github.com/hotdoujiang/e6064faca930a996230aa4dc3ccd8db0). Each point's radius encodes the number of people wounded or killed, with color set to a semi-transparent \"bloody red\" to visually emphasize severity. The visualization is built with React, D3 v5, and SVG, using the `d3.geoNaturalEarth1` projection for the map and `d3.geoPath` to render land boundaries and graticules. Point sizes are scaled via `d3.scaleSqrt` with a maximum radius of 13 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/278556d01b4044bd9aa8d1e1858a5d38?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
