• Increase title and axis label font size
• Implement population size filter
• Map chart - country IDs
• Map chart - Black outline for all countries when filter is applied vs only displaying the selected countries (TA feedback/ Client feedback)
• Add note on population density units (TA feedback)
• Add asterisk to Education Ratio and Population to draw attention to notes (TA feedback)
• Colour scale on world map changing (TA feedback)
• Drag and zoom functionality on map chart (Client feedback)
• Reorder legends, countries should be in the same order between both graphs
• Full layout on screen without scrolling (Client feedback)

We were able to implement all the feedback, except the following:

• Drag and zoom functionality on map chart (Client feedback) . Unfortunately zooming is not supported yet for the geo mark in vegalite Support pan and zoom for geoshape mark vega/vega-lite#3306

Additionally, we had to create a dummy value for the countries that did not fit the selection criteria in order to achieve the black outline for all countries when filter is applied vs only displaying the selected countries. Please see reflections.md document for more details.
