{"version":"1.0","type":"rich","title":"task4.9","description":"This bubble chart visualizes smartphone specifications, plotting storage capacity on the x-axis against RAM on the y-axis. Each data point represents a brand, with circle size reflecting battery capacity in milliamp-hours. The SVG rendering uses D3 v7 scales (`d3.scaleLinear`), axes (`d3.axisBottom`, `d3.axisLeft`), and a categorical color scale (`d3.scaleOrdinal`) to distinguish brands. A legend communicates battery size mapping, while hover effects increase bubble opacity. Data comes from an embedded CSV-style array of 16 phone models.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c4e27e16de14e6daf1bae2bafc58f40?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
