# 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, or a string for a
custom label. `edges` can be nonexistent.

Pan with WASD or arrow keys.  
Zoom with +/- keys.  
`r` to reload the default map.

You can drag and drop a JSON file to load it.

Both nodes and edges can have an extra object with metadata, some of which is
used by this program. An array called `offset` will adjust the positioning of
labels. An array called `color` will set the color via 0 to 1 RGBA values.

Added `areas` which are exactly like nodes except that they always draw a white
label and can have a custom radius specified. Drawn between edges and nodes.
Use transparency. 25% works well.
- TODO Options: box instead of circle, line instead of fill, ovals

## 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],
    "Hidden Node": [0, 0, 0, false]
  },
  "edges": [
    ["TestA", "TestB"],
    ["TestA", "TestC"],
    ["TestB", "TestC"],
    ["TestC", "TestE"],
    ["TestE", "TestFarLeft"],
    ["Hidden Node", "TestC", false]
  ]
}
```
