{"version":"1.0","type":"rich","title":"Activity6_question4","description":"This bubble chart compares major tech companies by research and development spending (x-axis) against revenue (y-axis), with bubble size encoding employee count and color distinguishing each company. It uses D3.js v7 to render an interactive SVG visualization, loading data from a CSV file. Hovering over a bubble triggers a custom tooltip showing the company's R&D spending, revenue, and total employees. A color legend on the right identifies each company, and the chart includes labeled axes with linear scales and a square-root scale for bubble radii.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cef5fe8832a948b68e0c3536b01a1f0e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
