{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows a multi-series line chart with a dropdown menu to switch between different data groups, highlighting one series at a time. The code uses d3.csv to load a dataset from a GitHub repository, then creates an SVG chart with d3.scaleLinear for axes and a d3.scaleOrdinal color scale based on d3.schemeSet2. Selecting a new group triggers the update function, which animates a transition on the path’s d attribute over 1000ms, changing its stroke color accordingly. The visualization is built with d3.v4 and includes an HTML select element populated with group names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6c5bb7f765a542ddb52fd0e9c2190c53?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
