of the first, which shows something of their origin. A node may technically
appear in more than one column, because web pages are organized by
sequence. The red down arrows indicate the end of the road for a subset of
paths.

Flow graphs can also show customer paths through a
website. Google Analytics provides this for analysts looking to boost
engagement and click-through.
Flow graphs can also be combined with small multiple charts to show flow
over time.
Figure 2-13
is an example of how financial transaction activity
between parties can be shown using Influent. Communities of similar nodes
are hierarchically clustered and summarized for scalability.
Figure 2-14
shows how flow of influence (in this case, steel consumption factors) can be
visible even when not easily quantifiable. Correlation of time series patterns
suggest complex relationships of cause and effect.
A left-to-right layout works brilliantly for indicating flow direction.
However, when there is frequently an exchange of flow in both directions,
you may want to use an alternative layout approach.
Figure 2-15
uses a
D3
chord chart
to show reciprocal flow by modifying the width of the
link on either end to reflect outgoing exports. The links in a chord chart
resemble two arrows that collide in the middle and swallow one another. In
this example, red links emphasize trade imbalance, and red country nodes
are net exporters. Green countries are net importers.
