{"version":"1.0","type":"rich","title":"task9-Q2","description":"This example shows how two session rates vary over time on the same date, with overlapping blue and yellow semi-transparent areas drawn from a CSV of time-stamped values. The chart uses D3.js v3 to parse the data, apply a time-scale for the x-axis and a linear scale for the y-axis, and render the areas with `d3.svg.area()`. Axis labels, a title, and the areas are all drawn as SVG elements within a single `svg` group, with axes styled via `d3.svg.axis()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/06c65e6dc16843f1b1fd3a56caacb6d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
