{"version":"1.0","type":"rich","title":"Massachusetts Advanced Placement Performance by town","description":"This visualization shows Massachusetts Advanced Placement performance by town, with each town’s score representing the number of students achieving a score of 3-5 on AP exams. A proportional symbol map uses circles sized with `d3.scaleSqrt` overlaid on a geographic outline rendered via `d3.geoPath` and `geoAlbers` projection. The map is built with React, pulling TopoJSON and CSV data through custom hooks, with static SVG rendering and semi-transparent green circles to emphasize performance density.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3645d45b2c549b18b0a2b7ba4c1a10a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
