{"version":"1.0","type":"rich","title":"Bubble/Bar Combo viz","description":"Four push buttons switch between quarters in a health dataset for traumatic brain injuries, updating a bubble chart and bar chart side by side. The bubble chart uses `d3.pack` and `d3.hierarchy` to size circles by visit counts for anxiety, neurology, sleep, and headache, while the bars show total TBI visits and symptoms. Buttons call an `update` function that re-binds data and transitions the SVG elements, demonstrating an interactive alternative to a time-series axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/283f97e8ce1a4f94955ff24cb51355a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
