Hello, Codeforces!

I've been working on a graph visualization tool for a while now, and because I couldn't think of a good name for it, I've opted to call it Another Graph Editor.

The layout is very much inspired by CS Academy's graph editor. Input is pretty straightforward too, as you may just copy paste the test case edge data into the text area using the form u v w, where w is an optional edge label. You do not need to enter n m, representing the number of nodes and vertices respectively.

Node labels are supported too! Suppose the problem offers an array a where a[i] represents the value at node i, you can just copy-paste it into Node Labels and it'll show up as little octagons hovering over the node. If you want to skip over a particular node (aka an empty label), use the character '_' as a placeholder.
