{"version":"1.0","type":"rich","title":"Assignment-6_Question-4","description":"This bubble chart visualizes the correlation between number of mentions, engagement rate, and reach for various hashtags. Each circle’s position maps mentions on the x-axis and reach on the y-axis, while its radius encodes engagement rate and its color distinguishes hashtag categories. The visualization uses D3 v7’s `scaleLinear`, `scaleOrdinal`, `d3.csv`, and event handlers for interactive tooltips. Axes, a legend for engagement-rate sizes, and a color legend are rendered in SVG, with hover effects that increase opacity and display detailed tooltip data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98ea814f4b9d4301b36aaf291752d485?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
