{"version":"1.0","type":"rich","title":"Activity 7 Tutorial","description":"A reusable scatter plot example demonstrates D3.js modular chart construction with local ES6 imports and a data-driven API. It loads NFL injury data from a GitHub gist, using `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to render points. The chart’s width, height, margin, and radius are configurable via function methods. A companion area chart illustrates yearly injury totals with `d3.rollup`, `d3.area`, and gridlines, while a pie chart displays injury-type percentages using `d3.pie` and `d3.arc` with a legend. The examples show multiple visualization patterns within a single tutorial.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28ae75586c4b496da4e3151533ea0558?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
