All sketches in Easik are saved as .xml files.
When opening a sketch, Easik reads the .xml file and generates the associated graph. To
open a sketch, click on File from the menu bar, and choose Open Sketch.... A dialog
box will then appear where the directory and file can be specified for loading. It is
also possible to access the Open Sketch... command through the shortcut keys ALT-O.
Once the file has been opened, the resulting sketch will be displayed and the name of the sketch will appear in the Easik title bar.
