A quadrant chart divides a scatter plot into four labeled sections, making it easy to classify data points by two measures at once. Built with the AnyChart JavaScript library, it is ideal for comparative analysis and strategic categorization.
This sample plots 30 countries by quality-of-life index and pollution index, with data sourced from Numbeo. Labeled markers identify each country, and ellipse annotations highlight the best and worst clusters. Tooltips display both index values for any hovered country.
See the Quadrant Chart documentation for all configuration options.
