01 / CONTEXT
The problem to solve
Make complex inequality indicators easier to explore and compare across countries and time.
02 / ENGINEERING
From need to system
- Extract and prepare selected World Inequality Database indicators.
- Build interactive D3.js views for measures such as income and Gini.
- Explore country groups including BRICS and related comparisons.
- Present the data through several complementary chart forms.
03 / DESIGN DECISION
A meaningful choice
Use visual encodings to support exploration while keeping the indicator and comparison context visible.
04 / EVIDENCE AND LIMITATIONS
What is actually documented
The public README documents data extraction, preprocessing and interactive D3 visualizations, including income and Gini comparisons. The project is exploratory rather than a policy analysis.
05 / NEXT VALIDATIONS
How I would strengthen the proof
- Add source notes and methodological caveats alongside each measure.
- Check comparability across countries and years.
- Modernize the visualizations and accessibility.
These are planned validation steps, not already measured results.
