{"version":"1.0","type":"rich","title":"Skyscrapers Histogram","description":"This histogram shows the distribution of construction start years for U.S. skyscrapers, with bins set at ten-year intervals. The chart uses `d3.bin` to group the data and `d3.scaleTime` with `d3.axisBottom` for the time axis. Bars are drawn as SVG rectangles, colored `cornflowerblue`, on a gray background with horizontal grid lines. The data comes from `skyscrapers.csv`, which is filtered to exclude rows where construction has not started.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51522d64269d443a9aad69f322cb7271?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
