Context We analyzed trade fair performance across Europe to understand the correlation between exhibitor volume, venue size, and visitor density.

Key Dimensions Analyzed 1. X-Axis: Number of Exhibitors (Commercial density) 2. Y-Axis: Visitors per Sqm (Crowd density/Popularity) 3. Bubble Size: Net Sqm (Physical scale of the event) 4. Color: Main Industry (Sector segmentation)

Based on the visualization:

1. High Density Niche: Events in the top-left quadrant have high visitor density but fewer exhibitors. These are likely highly specialized, “must-attend” vertical events.
2. Scale vs. Density: Larger bubbles (High Net Sqm) typically appear lower on the Y-axis. As physical size increases, maintaining a high “visitor per sqm” ratio becomes statistically more difficult.
3. Outliers: Use the “Show All Outliers” option in the dropdown to see the extreme performers that exceed 3 visitors per sqm.
