You can use this page to experiment with Multigraph. Paste a mugl file into the form below and click the "Submit Mugl" button to see the resulting graph, or to find errors in the file. Note that the tester can only display data that is contained in the mugl that you paste into the form below, or that is served from web services referenced in the mugl; it cannot display data from an external (csv) file. If you enter a mugl file that contains data in an external (csv) file via the "<csv>" tag, the tester will correctly validate the file and display any errors it contains, but the graph will not appear.
