{"version":"1.0","type":"rich","title":"Boxes Population of Towns on the South Shore Of MA","description":"A grid of color-coded squares displays the population of eight Massachusetts South Shore towns for a selected year, with each square showing the population, annual percent change, and town name. The fill color maps from red to green based on percent change, using the D3 `interpolateRdYlGn` color scale with a legend. A slider updates the displayed year, re-rendering the visualization with data from CSV files loaded via D3's `csv` module, and the React app manages the state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd8280e02083447087ab86f3dc94b14c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
