These maps are easy to create with only a few simple parameters to set such as size and map centre. All the code is generated by the provider and need only be inserted to the page.
These examples are framed in a minimal way so the key map code is visible. Simple comments to show where the code begins and ends are provided.
The most obvious difference is that the Google code is a single line and the additional features are encoded in that line. The Bing code has the two options for directions and viewing a larger map are separate. These could be styled separately.
