M Chart is a WordPress plugin for creating interactive charts and graphs. Data is entered through a spreadsheet-like interface directly in the WordPress admin, and charts are embedded in posts and pages using a shortcode or block UI. Charts render as interactive JavaScript by default, with an automatic fallback to a static PNG image in RSS feeds, Atom feeds, and AMP pages.

M Chart supports two charting libraries: Chart.js (the default, MIT licensed) and Highcharts (optional, requires a separate plugin). See Libraries for guidance on choosing between them.
