Typos in Diagram Scene Example

I think there are some typos in the Diagram Scene Example page in the documentation:

• "The is the createMenus() function:" should say "Here is the [...]" instead.
• "We create the three menus' of the example." shouldn't have an apostrophe: "menus".
• "The widgets created with this function is used in the tool box." should be "The widgets [...] are used in [...]"
• "[...] or an arrow may be connected between to diagram items." should be "two".
• "[...] share responsibility for the examples functionality." should be "example's".
• "[...] we create the items polygon according to diagramType." should be "item's".
