As social media is arising, users are willing to convey their opinions, make comments, and share posts. This research used D3 to design three visualization tools: the post of heat graph, the fan page of heat graph, and the association of fan page graph respectively. Using these three visualization tools, we can track issues in different ways: With the post of heat graph, we can find the influence of the fan page's post on specific issue and time; the fan page of heat graph, we can realize the rank of the fan page's influence and the posts' influence; and the association of fan page graph, we can realize the relationship between fan pages and the issue.
