A scatter chart is a statistical graph used to display the relationship and distribution pattern between two variables. Each data point is represented as a dot on the chart, with the horizontal and vertical axes corresponding to the values of the two variables. By observing the distribution of dots, you can analyze correlations, trends, and outliers between variables. This tool supports multiple data series, custom colors, point size configurations, and allows exporting charts as PNG or SVG files. Suitable for correlation analysis, data distribution studies, outlier detection, trend forecasting, and other visualizations involving two-variable relationships.
