Visualization Implementation 3

Three thigs that I learnt through the tutorials:

Using "div" tag to include two separate codes in a single .html file.
Creating eye pleasing Animations and Transitions using D3. Learning how to do transitions with different shapes and also by changing colors was the best experience.
Plotting a scatterplot by defining X and Y axis.
