{"version":"1.0","type":"rich","title":"STUDY GUIDE","description":"This example demonstrates common data-manipulation patterns in D3, showing how to calculate averages, search arrays, sort objects, and combine datasets using JavaScript loops and D3 methods like `d3.mean` and `d3.ascending`. It also includes commented code for loading CSV data, building tooltips with HTML tables, and preparing geographic path data for SVG rendering. The visualization is a study guide presented as code snippets in the browser console, using D3 v4 with SVG output, and relies on built-in array methods such as `forEach`, `includes`, and `sort`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ccb96a54ea7ec62b7f9b051258b62668?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
