{"version":"1.0","type":"rich","title":"activity 7.2","description":"This visualization uses an area chart to show the relationship between study hours and the corresponding grade values (A=4, B=3, C=2, D=1) for individual students. The chart’s fill uses a linear gradient transitioning from rose to blue to green. The code loads a CSV from GitHub, filters for entries with study hours and grades, maps letters to numeric values, and sorts the data by study hours before creating a smooth monotone-X curve. The axes are drawn with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00adf9e82e0e4b8297cbd3f82f199b7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
