<p>Grouping a network doesn't simply group the data. It creates a
function that loops over all the input data you give it. So if you
have, say, a list of 100 random numbers connected to a network
containing a single rectangle, the network will be executed 100
times, each with the same single rectangle.</p>
<p>This behaviour is actually quite useful since it allows you to
put separate functionality in subnetworks. We use it for example to
create a single element of a data visualisation, then having that
element repeated for each input row of the visualisation.</p>
<p>For more info on list matching and other NodeBox concepts, you
can read the <a href=

<p>Hope that helps,</p>

extremely useful! I found a work around. I'm perfectly sure you are
right, I just need to digest it I guess. Anyway, this was the
result: Cycle Flows on the TFL Road Network:</p></div>rorytag:support.nodebox.net,2012-11-01:Comment/361391762015-02-25T20:37:50Z2015-02-25T20:37:50ZData Duplication<div><p>Nice!</p></div>Frederik De Bleser
