Fixed dimensions are useful to simply tell a story. In some case, we need high cardinality dimensions that we can not list. We can provide the cardinality in the conf file, and generate dimension values as label_number where number is in [1,cardinality]

If this is something we would like to automate, we can add a conf section with the metrics/dimensions to overwrite together with the new values and filters

Random metrics are suitable for certain use cases. For other, we need different distribution to be realistic. This issue track the addition of new distributions. Add comment to suggest a new distribution
