{"version":"1.0","type":"rich","title":"feat1_dropdown_dependent_barchart","description":"This example presents a dropdown-driven bar chart comparing height and weight percentages across geographic blocks. Users select a metric from the dropdown, triggering a smooth 1-second transition that updates bar heights, fill colors, and the y-axis scale. The visualization uses D3 v5 with d3.scaleBand and d3.scaleLinear for positioning, a sequential color scale for encoding values, and transition methods for animated updates. Data comes from a local CSV file, rendered as SVG rectangles with tooltips that display block names and values on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/739257b8940f4f4c81ce686e93fb274e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
