A scatter plot displays smartphone models by price on the x-axis and battery life on the y-axis. Each dot encodes brand through color and average rating through size, with a legend explaining the mappings. Built with D3 v7, the visualization uses SVG rendering and includes interactive tooltips that appear on hover. The data comes from a CSV file fetched via URL and parsed with D3's CSV parser, with custom text preprocessing to handle single-line formatting. Axis gridlines and styled panels enhance readability within a dark theme.
