Colors
The colors used, can be overwritten in the Policy diagramChartJSColors.
The structure of the policy is very strict.
The policy has to be formatted as a js array of strings that represent an rgb color.
Thus: It has to start with [ and and with , ].
Each color has to be formatted as an rgb color and wrapped with ', and separated by , eg 'rgb(255, 255, 255)', for a white color
