{"version":"1.0","type":"rich","title":"Activity_6-Question-4","description":"This bubble chart visualizes the correlation between three metrics for various hashtags: number of mentions, engagement rate, and reach. Each circle's x-position maps to mentions, y-position to reach, and its radius encodes engagement rate, with color distinguishing the hashtag. It includes a legend for engagement rate values and a color legend for hashtags. Built with d3.v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.schemeCategory10` for encoding, and renders as SVG with interactive tooltips on mouseover. The data comes from the provided `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b1b3caf30db45a584587fbb0d6b6de3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
