{"version":"1.0","type":"rich","title":"activity 6_ task 6","description":"This example visualizes advertising data from a CSV file, plotting TV spending against Radio spending using a scatter plot with colored circles that also encode Newspaper and Sales values through their radii. The visualization is rendered as an SVG using D3 v6, with scales created via `d3.scaleLinear` and axes generated through `d3.axisLeft` and `d3.axisBottom`. Data is loaded asynchronously using `d3.csv`, with each row parsed to numeric values before mapping to screen coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c7d6fb7bcf0446aab124a096ba3564a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
