{"version":"1.0","type":"rich","title":"Bar and Line chart","description":"This example combines a bar chart of effective rainfall with a line and circle overlay of water level, both plotted against a shared time axis. The dual y-axes use independent linear scales, while the x-axis uses a time scale. Built with D3 v5, it renders to SVG and supports zooming via `d3.zoom`, which rescales all axes and re-renders bars, circles, and a line path generated with `d3.line`. The data is loaded from two CSV files hosted on VizHub. The chart initially displays the full dataset before user interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce2acb31caac40e4bcc17abab4208c88?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
