Easy management of graphs

Each graph created in CanoDraw and saved to a file remembers, on which CanoDraw project is it based, and it is also able to open this "parental" project if asked to do so (unless the file location has changed). Similarly, each CanoDraw project maintains a list of CanoDraw graphs created from it and it is again able to offer you a selection of graphs to be opened:

When opening CanoDraw projects or graphs, customized File Open dialogs summarize project properties or graph contents before the files are opened in CanoDraw workspace.
