{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This dashboard displays 180 days of synthetic student performance data, presenting study hours, practice tests, and scores. One card shows a multi-series line chart with dual y-axes, plotting study hours and practice tests on the left and score on the right, using `d3.scaleLinear` and `d3.line`. A second card combines a bar chart of practice tests with a line for average score, using `d3.select`, `d3.append`, and `d3.scaleTime`. The data is generated client-side with a seeded random number generator and a downloadable CSV is provided via a custom `toCSV` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eb563b4a01294d949b357cf058773218?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
