## 6 Additional Use Cases from Related Policy Domains
### Global Food Security Analysis  
The first implementation focuses on global food security metrics across countries, providing comparative analysis through interactive visualizations. The implementation combines choropleth mapping for spatial analysis with detailed metric comparisons using Streamlit; see Figure 10. This visualization story enables policy-makers to:  
* Compare food security scores across different geographical regions. * Track temporal changes in food security metrics between 2019 and 2022. * Analyze the relationship between different food security dimensions through radar charts. * Identify leading countries and potential policy models through ranked comparisons.

In particular, our analysis of the Global Food Security Index dataset through interactive visualizations revealed several significant patterns and policy-relevant insights. The comparative analysis of food security scores between 2019 and 2022 highlighted notable regional variations and the impact of global events. For instance, countries like Finland and Spain demonstrated marked improvements in their food security metrics, with Spain showing progress in affordability metrics, suggesting successful economic policies enhancing purchasing power. In contrast, countries like Germany and Singapore experienced significant declines, albeit for different reasons. Germany's decline was primarily driven by reduced availability scores, potentially reflecting supply chain disruptions from the Ukraine conflict, while Singapore's decrease was concentrated in quality and safety metrics, possibly due to shifts in food import sources amid global trade tensions.

The ranking analysis of top-performing countries reveals a strong Nordic presence, with Finland, Ireland, and Norway leading the global rankings. This clustering suggests the effectiveness of regional policy approaches and the potential benefits of policy transfer within geographic regions. The radar chart analysis provides deeper insights into these performance patterns. For example, while some countries maintained relatively stable overall scores, the underlying dimensional changes tell a more complex story.
