This bubble chart visualizes the relationship between average camera resolution (megapixels) and average battery capacity (mAh) for various smartphone brands, with bubble size representing average screen size in inches. Each brand is color-coded using a categorical Tableau10 palette. The chart uses D3’s linear scales for the x- and y-axes, a square-root scale for bubble radius, and an ordinal scale for colors. Hovering over a bubble displays a tooltip with the brand name and the exact values for battery, camera, and screen size.
