Line Graph Maker
Line Graph Maker builds line charts in your browser from comma-separated labels and values. Add a title, horizontal and vertical axis labels, pick linear or logarithmic Y-axis scaling, adjust line tension from 0 to 1, and download the finished chart as PNG, JPG, or SVG without creating an account.
Spreadsheet charting means rows, columns, and export dialogs. Line Graph Maker strips that down to a single form: paste your data labels, paste matching values, toggle grid lines and legend placement, and download. The same site family also hosts bar, pie, doughnut, scatter, and radar chart makers for quick one-off visuals.
Students, teachers, and bloggers use it when they need a clean line graph for a slide, report, or blog post without opening Excel or Google Sheets. The tool is free, runs entirely in the browser, and was built as a side project by a small developer team still adding features.
