+# World6-travelmap
+I made a little program for displaying a simplistic graph of nodes and edges to
+make a travel network with calculated distances... specifically for my Minecraft
+World.
+
+Data must be in a map.json file. `nodes` is an object with named arrays of info.
+Each node is an `x`, `y`, and `z` position. The optional 4th item is `true` to
+display the node's name, a string to display *that* as the node name, or `false`
+to completely hide a node. `edges` is an array of arrays of two names of nodes.
+An optional 3rd item can be set to `false` to hide an edge.
+
+- TODO: Make drag and drop loading of a JSON file possible. :D
+- TODO: Make it not error with no map file.
+
+## Example JSON
+
+```json
+{
+  "nodes": {
+    "TestA": [100, 0, 100],
+    "TestB": [150, 0, 200],
+    "TestC": [300, 0, -200, true],
+    "TestE": [1200, 0, 200, "Displayed Name"],
+    "TestFarLeft": [-200, 5000, 50],
+    "TestFarBottomRight": [1200, 0, 2000, true],
