[[https://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msg_id=0001OR][Sparklines]] such as [[figures/sparkline.png]] are tiny charts that are often embedded in tables. Again, hovering the mouse over the line shows the *exact value* at that point. Maximum and minimum values over the displayed range are indicated with red dots.

An array of bifurcating unidirectional flows (of bits and bytes, in our case) can be nicely visualized using the [[https://en.wikipedia.org/wiki/Sankey_diagram][Sankey diagram]]. Here is an example:
An array of bifurcating flows (of bits and bytes, in our case) between two sets of entities can be nicely visualized using the [[https://en.wikipedia.org/wiki/Sankey_diagram][Sankey diagram]]. Here is an example:

The interactivity of this diagram is twofold:
The interactivity of this diagram is twofold:
- Hovering the mouse over one of the entitities represented by coloured bars (on the left or right) renders the flows sourced from or sinking in that entity in darker grey, and also displays a box with quantitative information.
- Hovering the mouse over one of the entitities represented by coloured bars (on the left or right) renders the flows sourced from or sinking in that entity in darker grey, and also displays a box with quantitative information.
- Hovering the mouse over one of the lines emphasizes the particular flow and displays info about it.

Similar to the Sankey diagram, the [[https://en.wikipedia.org/wiki/Chord_diagram][Chord diagram]] is used for visualizing mutual quantitative relationships, but this time within one set of entities:

The interactivity features are similar to the Sankey diagram. Again, a single flow or all flows belonging to an entity can be displayed and quantified by mousing over them.
