Show venue map on hover

Is your feature request related to a problem? Please describe.

A module may offer lecture/tutorial classes in several venues in different parts of the campus. Many students, especially first-years (like me), are not familiar with all of these venues yet, so have to toggle between the timetable and the "Venues" section lots of times before deciding the best class to select (small distance from MRT station/hostel, small distance from other classes on the same day, small distance from canteens etc.)

Describe the solution you'd like

A little map showing the venue location is displayed when the venue name in the "timetable cell" is hovered on.

Describe alternatives you've considered

N/A

Additional context

For example, I'd like a small map of TP-SR5 being shown when the text "TP-SR5" is hovered on.

Start by inspecting the timetable cell and the existing “Venues” section to understand how venue names and locations are represented. Confirm how a map can be shown on hover for venues such as TP-SR5; done means hovering a venue name displays its location map without requiring navigation away from the timetable.
