- Dynamic sizing (sized to fit the Canvas element it’s on)
- Settings. These can be dynamically changed, and easily set outside of the streamgraph code.
- Zoom. You can click and drag to zoom in, and press Escape to zoom out.
- Hover. The selected layer changes color, and the active layer name and data point is displayed at the top of the screen.
- Another color option that offers a bit more variation.
- Examples (including the original beautiful examples).
It isn’t quite up to the New York Times version, but still impressive.
Jeff Clark has built some interesting information visualization tools to visualize Twitter results. Shown above is a “Twitter Streamgraph” for the term “SGI”, which obviously spiked heavily yesterday on the news.
The StreamGraph shows the usage over time for the words most highly associated with the search word. One of these series together with a time period are in a selected state and coloured red. The tweets that contain this word in the given time period are shown below the graph. You can click on another word series or time period to see different matches. In the match list you click on any word to create a different graph with tweets containing that word. You can also click on the user or comment icons and any URL to see the appropriate content in another window. If you see a large spike in one time period that hides the detail in all the other periods it will be useful to click in the area to the left of the y-axis in order to change the vertical scale.
He also makes Twitter Venn Diagrams where you can compare pairs or trio’s of words. Click inside to see a Venn Diagram of “SGI” vs “Rackable” vs “acquire”.
