Select meta property
To turn a regular property into a meta property, select the checkbox "Meta property" in the editing form of the property.
Adding a "color" meta property
Add a property with the meta type set to "color". Now whenever you create a node with value being a hexadecimal color code, it will be used to change node color in the graph.
Adding a "size" meta property
Add a property with the meta type set to "size". Now whenever you create a node with the value being a number, it will be used to change the size of the node in the graph.
Adding a "Gephi config" meta property
Add a property with the meta type set to "Gephi config". The value for this property will be used to change multiple properties in the graph: color, size and position.
The value should be formatted as JSON, with a specific format that comes from Gephi software, for example:
{ "color": { "r": 0, "g": 158, "b": 217, "a": 1.0 }, "size": 41.75, "position": { "x": -111.989075, "y": -1903.8099, "z": 0.0 } }
