Scatter Plot Maker

Scatter plots are one of the fastest ways to understand the relationship between two numeric variables such as ad spend and sales, study hours and scores, or clicks and conversions. A table alone often hides trends and outliers that become obvious the moment you place each pair on a chart.

This scatter plot maker reads simple CSV-style x,y pairs and draws an SVG scatter plot while calculating the correlation coefficient, R², and regression line equation. You can customize the axis labels, chart title, point color, and point size. Automatic tick marks and a data range summary make it easier to read values and understand the spread of your data.

It is useful for lightweight analysis, report preparation, classroom teaching, QA notes, and business KPI drafts. Export to PNG, SVG, or CSV for report embedding and data reuse. For related data work, use [Histogram Maker](/en/data/data-histogram-maker/) to inspect distribution shape, [CSV Chart Visualizer](/en/data/csv-chart-visualizer/) for other chart styles, and [TSV Viewer](/en/data/tsv-viewer/) to inspect tabular text.
