{"version":"1.0","type":"rich","title":"multiline chart","description":"Two overlapping line charts compare daily open and close prices from a small CSV dataset over a three-week period in spring 2012. One line is drawn in light gray for the open values, the other in sky blue for the close values, both against a shared time axis and linear price scale. The visualization uses D3 v4’s `d3.line` with `d3.scaleTime` and `d3.scaleLinear`, rendering SVG paths and axes via `d3.axisLeft` and `d3.axisBottom`, with data parsed using `d3.timeParse`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-8fcf0d1f389633eef7e21589b8c74012?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
