**Is your feature request related to a problem? Please describe.**
I'm using my edge labels to identify the type of relationship between two nodes. However, in my application logic, I also store a timestamp of when the data relationship has been updated. I'd like to be able to have a "heatmap-like" visualization where older relationships (and nodes) are slightly discolored / darker / less opaque relative to more freshly updated entities.

**Describe the solution you'd like**
Ideally, I'd like to be able to set a flag like `%%oc -d $display_var -l 50 -g cluster_id -de $edge_display --edge_colorize PROPERTYNAME`. ... and then you do the calculation :)

**Additional context**
Current workaround, run the same query with different properties as the edge labels
