This week I focused on the main page of how this post was shared.
I realized that it is the influencers who have a large number of friends matter and so I used four different colors to different shares with the different number of friends(more than 3000 friends,2000 to 3000 friends,1000 to 2000 friends and less than 1000 friends).
Since the group connections of sharers are weak,I added some white oblique lines above the color to distinguish sharers in listed influencing groups and showed the list of influencing groups sorted by the number of group members directly(including links to each group).
I used hexagons which are easy to connected with each other to replace circles.
The layout was not great so I changed it slighting as following and made the list of groups a separate page.
