Diagram won't render. Maximum nodes per "type" about bihisankey

[Neilos]

I'm not sure what you mean. The library should group your data by type into a hierarchical structure for you (that's the point of the library). Can you post your code?

Sorry for the delayed response. I understand that your library should group my data by type but what I was trying to explain is that for the data I have it won't group them into types. It just shows nothing at all.

I am using your example from blocks. I made a minor change to your app.js by changing the size of the svg.

So this is the data I'm trying to graph

var nodes = [

As you can see I generate the type nodes and add them to the node list. When I run this data I get no errors but a blank page although looking at the elements it looks like the data is there just not being rendered.

if I comment out the line:
nodes.push.apply(nodes, typeNodes);

and reload the page I get so from what I can understand the data is fine but when trying to group that many nodes it seems to break your library.

You can see the full code here: app.js

So after some more investigation I have worked out what the issue is.

The order of the nodes is important! The issue was that i was adding the type nodes at the end of the array which caused them to be rendered last after making space for all the other grouped nodes. If i make the height around 4500 and scroll down to the bottom i could find the diagram. Chaging the order of the nodes so the type nodes were first in the array fixes the issue. I would suggest you add a function that checks all nodes for if they are a type node (has no parent) and render those first to prevent this issue. Or at the very least mention it in your documentation.
