{"version":"1.0","type":"rich","title":"MultiLine with tooltip","description":"A multi-line chart displays several vital-sign measurements over time for a single patient, with each line colored by metric type. The visualization uses D3 v5 to render SVG paths and includes a custom tooltip that appears on hover. The code relies on d3.nest, d3.line, d3.area, and d3.scaleOrdinal, with jQuery used for tooltip interactions. Data comes from a local CSV file with patient measurements. Mouseover events highlight the hovered line and dim the others, while a vertical gridline helps compare values across time points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9838d5b78784d5bb4c48ce7c1236254?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
