{"version":"1.0","type":"rich","title":"Multiview for Cities Ranked by Number of skyscraper Completed Structures with improve performance optimaization","description":"This interactive visualization combines a world map with a time-series histogram to explore skyscraper construction across cities. The map displays each city as a triangular mountain, with height encoding the total number of completed structures over 100 meters, while color distinguishes countries. A brushable histogram below filters cities by the date of their first building over 150 meters. Built with React and D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for the map, `scaleLinear` for heights, and `brushX` for interactive filtering. Data comes from a CSV of city building counts with coordinates added manually.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98b6c46d518f4c9994cc146475fc90c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
