Feature - Map Grid to support multiple maps

[elenatorro]

To Do:

• Image:

  • Use html2canvas to display visualizations as an image

• Legends:

  • [ ] Example using helper methods with default legends (and how to disable them when using the grid, for instance) next
  • [ ] In MapGrid maps, we could add legends horizontally below / above the map next

• Publishing:

  • [ ] How an interactive MapGrid will be published? next
  • [ ] Would be possible to publish a MapGrid image, so we can access it by URL? next

• Parameters:

  • [ ] show_attribution: to display / hide attribution information It's displayed in the last map
  • viewport: to set a common viewport to all the maps
  • other parameters? (i.e.: basemap)

• Others

  • Set attribution expanded by default, instead of showing a button.
  • Test many complex visualizations to check notebook performance issues

Suggestion: thinking about global settings, shared among different Maps:

• viewport
• basemap
• attribution

I think that the work that has already been done is awesome, really. I wouldn't try to improve it now because it's already giving a lot of value. Here are my thoughts about each topic:

• Legends: don't worry about them right now. The customer shouldn't use helpers with grids but if they use them, we will improve it in the future.
• Publishing: I wouldn't allow to publish a MapGrid for now. We will work on it if it makes sense in the future.
• Parameters: I wouldn't allow them for now.
• Expanded attribution by default: I think it makes sense.
• Test performance: let's do one test to see what happens.
