{"version":"1.0","type":"rich","title":"Homework 6","description":"This interactive scatterplot from D3 v7 uses an SVG canvas to explore the relationship between GDP per capita and CO₂ emissions per capita, with points colored by world region and a legend on the right. The visualization supports both hover-based tooltips that display detailed text and click-to-select functionality, with a toggleable 2000ms tooltip delay button for testing responsiveness. Data loads from a CSV file via `d3.csv` with `d3.autoType`, axes are rendered with `d3.axisBottom` and `d3.axisLeft`, and the chart uses `d3.scaleLinear` for both axes and `d3.scaleOrdinal` with `d3.schemeTableau10` for color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/547cbc1a6e2348eaaed0a6033a1cde7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
