{"version":"1.0","type":"rich","title":"Marks and Channels_NH_2","description":"This example visualizes daily solar energy production data from a Bloomington Parks & Recreation site by encoding wattage values through bar length. The visualization arranges seven rectangles along an x-axis, where each bar’s height corresponds to the wattage measurement for a given day. The implementation uses D3 v7 with a band scale for positioning the bars and renders them as SVG rectangles. Color is applied via the `schemeCategory10` palette, and the code structure separates the bar-drawing logic into a reusable `length` function that receives the dataset and height parameters.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ccb4a6946e83473190677ad2b5590e80?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
