{"version":"1.0","type":"rich","title":"HAW: Bday Data viz","description":"This visualization compares annual birth statistics across four years by rendering each year as a hospital building, with the number of birth dots inside representing relative crowdedness. React manages the component state and container sizing via a custom `useContainerDimensions` hook, while D3 v7 handles SVG rendering and data joins through `d3.select` and `d3.csv`. The chart pulses with an interactive hover effect on hospital bodies, and the code explicitly generates synthetic multi-year data by applying variations to the loaded CSV totals from `data.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37ea0992e34648b988d95fe122f79359?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
