title: "Just 25 Companies Hold Half of Brazil's Corporate Capital"
subtitle: "Analysis of 141,332 firms shows a Gini Coefficient of 0.998, indicating near-total wealth capture."
description: "This visualization explores corporate capital concentration in Brazil using Lorenz curve analysis of 141,332 companies from the CNPJ open registry. A dual-panel approach reveals extreme inequality: the traditional Lorenz curve shows capital hugging the bottom axis, while a zoomed view of the top 0.6% exposes that just 25 companies control half of all corporate capital."

##### 📦 Custom Helper Functions
This analysis uses custom functions from my personal module library for efficiency and consistency across projects.
**Functions Used:**
- **`fonts.R`**: `setup_fonts()`, `get_font_families()` - Font management with showtext
- **`social_icons.R`**: `create_social_caption()` - Generates formatted social media captions
- **`image_utils.R`**: `save_plot()` - Consistent plot saving with naming conventions
- **`base_theme.R`**: `create_base_theme()`, `extend_weekly_theme()`, `get_theme_colors()` - Custom ggplot2 themes
**Why custom functions?**\
These utilities standardize theming, fonts, and output across all my data visualizations. The core analysis (data tidying and visualization logic) uses only standard tidyverse packages.
**Source Code:**\
