Tools to Visualize MITRE ATT&CK Mappings for Detections

The author of the post is looking to remap MITRE ATT&CK tags onto SIEM/XDR detection rules for a new client. They aim to create a heat map to visualize which detection rules cover which techniques, specifically from different sources and tools. However, they are facing difficulties in finding the appropriate method for this visualization, although they can extract the detection rules and their techniques via PowerShell.
