{"version":"1.0","type":"rich","title":"activity6_Task4","description":"This visualization is a bubble chart that shows the relationship between student age, course, CGPA, and year of study, using data from a mental health survey. The x-axis maps age, the y-axis maps course, bubble size represents CGPA, and color distinguishes year of study. D3 v7 API calls such as `scaleLinear`, `scalePoint`, and `scaleOrdinal` are used to position and style the circles, while `d3.csv` loads the data and `d3.axisBottom` and `d3.axisLeft` render the axes. The chart is rendered as an SVG with a tooltip for interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6fabc042114e46dc96fe0dee8160dc67?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
