Heart Data Analysis Dashboard

Resting Blood Pressure: Blood pressure tends to increase with age for both males and females, with noticeable fluctuations around ages 55–65.
Chest Pain Type vs. Age: Severe chest pain is most common in older individuals, averaging around 63 years, while mild and moderate cases are observed in younger age groups (around 51–55 years).
Serum Cholesterol: Cholesterol levels show a gradual increase with age, with several outliers beyond 300 mg/dl in individuals aged 55 and above.
Heart Rate and Chest Pain:
- Individuals with moderate chest pain tend to have higher average heart rates (around 166 bpm for females).
- Males generally exhibit lower average heart rates across all pain types compared to females.

Presence of Heart Disease:
- Heart disease is more prevalent among those with severe chest pain in both genders.
- Older females with severe chest pain show the highest proportion of heart disease cases (63.25%).
Exercise-Induced Angina: People experiencing exercise-induced angina show higher average maximum heart rates compared to those without, indicating a potential stress response link.

France ranks 1st globally, indicating the best overall health system among the 49 countries analyzed.
There is a clear inverse relationship between health investment per capita and health quality ranking — higher spending does not necessarily translate to better healthcare outcomes.
The United States, despite investing approximately $9403 per capita in healthcare, ranks only 38th, suggesting inefficiencies due to heavy private-sector spending.
European countries dominate the top ranks, with many nations from Western and Northern Europe represented — showcasing strong public healthcare systems.
No countries from the Global South are represented in the top 49, reflecting persistent disparities in global health infrastructure and investment.
The map visualization shows that North America and Western Europe spend significantly more per capita on healthcare compared to Sub-Saharan Africa and South Asia.
Private vs. Public Spending: Larger dark circles indicate higher private health expenditure, whereas lighter circles represent total health expenditure — highlighting a trend where private-sector dominance often correlates with poorer overall rankings.

Global CO₂ Emissions Trends: Most regions show fluctuating emission growth rates between 2000 and 2016, with a sharp decline around 2016, likely linked to changing industrial or environmental policies.
Regional Insights:
- Eastern and South-Eastern Asiahas the highest average CO₂ emissions from fuel combustion, followed by Europe & North America.
- Sub-Saharan Africa and Oceania report the lowest emissions levels overall.
Top Emitting Countries:

The United States leads in total greenhouse gas emissions, followed by China and the Russian Federation. Japan, Germany, and Brazil also rank among the top contributors.
Corporate Reporting:
The United States, United Kingdom, and China have the largest number of companies reporting on sustainability metrics, reflecting stronger climate accountability frameworks in developed economies.
Geographic Distribution:
The global map reveals that higher emissions are concentrated in industrialized nations, while developing regions, especially in Africa and parts of Asia, contribute less but are more vulnerable to climate impacts.
Equity & Representation:
Once again, the Global South is underrepresented in emission reporting data, underscoring disparities in sustainability infrastructure and monitoring capacity.

Global Workplace Score Trends: Scores have steadily improved from ~30 in 1980 to ~80 in 2024, reflecting progress in gender equality laws globally.
Regional Insights:
- High-income OECD leads with the highest average Workplace Score (~80+), setting the benchmark for gender equality standards.
- Regions like Sub-Saharan Africa and Middle East & North Africa lag behind (~30–40), indicating significant gaps in workplace rights.
Legal Rights Indicators:
Many economies still lack legislation on sexual harassment and equal job access, despite global improvements.
Economy Distribution:
OECD economies represent ~25% of the dataset, while developing regions account for smaller shares but face greater challenges.
Gender Equality Benchmark:
OECD countries consistently outperform other regions, highlighting disparities in workplace protections and enforcement.
