The data shown here comes from Privatization of Space.

This is an unfinished project(also the reason why it doesn't have a proper title), right now it has the following several effects: zoom in/out, drag, selectable countries, reverse triangle points, tooltip.

I think the most difficult part is the selectable countries, which I learned from here. I had to re-construct my whole code structure and encountered several problems along the way and got stuck for a long time, but in the end it worked out, alought not perfect, and that's for the next few days.

In the next 10 days I need to add: pie chart or divided color area for each countries showing the ratio of private/state launches, multiple views with a bar chart at the bottom showing Total Number of Rockets Throughout The Years.
