Show HN: I put employees inside S&P 500 market-cap bubbles

Project Showcase: Big Whale Hunting

This project explores the intersection of corporate valuation and human capital by placing employees inside market-cap bubbles for S&P 500 firms.

📊 The Visual Logic

The visualization uses a geometric approach to represent corporate scale. The fundamental relationship is defined as:

Bubble Area∝Market Capitalization\text{Bubble Area} \propto \text{Market Capitalization}Bubble Area∝Market Capitalization

Inside these bubbles, individual stick figures represent the workforce. This creates a visual shorthand for efficiency and valuation:

  • High Density: A bubble packed with figures indicates a lower market value per worker.
  • Low Density: A large bubble containing only a few figures indicates a massive valuation per employee.

"A bubble crowded with small figures is worth little per worker and a big bubble with a handful of figures is worth a lot."


🛠️ Technical Implementation & Filtering

To maintain clarity, the dataset is filtered. All companies are shown Only a specific subset of the S&P 500 is included based on these criteria:

  • Minimum employee threshold met.
  • Minimum market capitalization reached.
  • Inclusion of specific outliers (e.g., Palantir and Welltower), which are represented by half-size figures due to lower staff counts.

The data is sourced from the most recent annual reports, meaning the employee_count variable may lag by up to one year.
