The server compiled successfully. Let me check if there are any runtime errors by adding debug logging and also verify the component exports:

Let me add console logs to debug and trace the data flow:

There's actual data in the database (27 participants, 11 exhibitors, 4 firm leaders). Let me scroll down to see the Venue Preferences section:

I can see the issue now. The charts ARE rendering with the tabs ("1st Choice" is visible and selected), but the data being displayed is showing the raw JSON arrays like [\"Hotel/Conference.... This means the data from the database is coming in as JSON strings rather than actual arrays. Let me check the database column type and fix the processing:

I see the issue - when the data comes from the database as a JSON string (like '["Hotel/Conference center","University campus"]'), we need to parse it. The code currently checks if it's a string and treats it as a single value. Let me fix the parsing to handle JSON strings:

Now let me also fix the same issue in the processWeightedRankingData function:

Now let me also fix the same in processRankingData:

Now let me remove the debug logs I added earlier:

Now let me verify the fix is working:

The histograms are now working correctly. The tabs show all 6 choices (1st through 6th) and the data is properly parsed showing actual location names like "Downtown Boston", "South Shore", "Route 128 corridor", "North Shore" instead of raw JSON strings.

The issue was that the ranked choice data was being stored in the database as JSON strings (e.g., '["Downtown Boston","Route 128 corridor"]') rather than native arrays. I updated the three ranking data processing functions (processRankingData, processWeightedRankingData, and processRankingByPosition) to detect and parse JSON string arrays before processing them into the histogram data.

Great! The tabbed histograms are now displaying properly. You can click through the tabs (1st Choice, 2nd Choice, etc.) to see the distribution of how many times each location or venue type was selected at each ranking position. The bars are sorted from most chosen to least chosen within each tab, making it easy to see which options are the most popular first picks versus common backup choices.
