{"version":"1.0","type":"rich","title":"Lego Sets by Year from Rebrickable","description":"A bar chart visualizes the cumulative number of LEGO sets released each year from 1949 to 2019, using data from Rebrickable. The chart shows a steady upward trend over time. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to render the SVG output. The `csv` function loads the data, which is parsed and plotted with rectangles, while custom tick intervals are defined using `d3.timeYear`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/786133a492454de882950a58c4de1a41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
