Question
Modify my Javascript project codes to change position and add style. It's a Zoomable Treemap.
http://math.mercyhurst.edu/~swang/courses/MIS_370/finalproject/countries.html
I want someone to help me to modify this to:
1. Parent title on the top, four children Asia, Americas, Europe, Africa Oceania on the 5 distinct places, left up and down, right up and down, bottom.
2. Every child still has the same function. It still can click and check Population. But every time user chooses one child, 4 other children will disappear, only the chosen one will be bigger.
3. Add a bootstrap for web style. Make it looks beautiful.
Thank you so much!
