{"version":"1.0","type":"rich","title":"Activity 6_Task 3.2","description":"This example builds a scatter plot with a categorical legend, where data points are distinguished by shape. The visualization maps two quantitative variables to the x and y axes using `d3.scaleLinear` and assigns a different symbol to each category via `d3.scaleOrdinal` and `d3.symbol`. The chart includes axes with labels, drawn using `d3.axisLeft` and `d3.axisBottom`, and a custom legend that displays the shape mapping. The underlying data and its source are not specified in the provided code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2051fba770b142258e9be1d37e3d3e11?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
