Heart Disease Age Distribution Visualization

This interactive visualization displays the age distribution of patients, separated by heart disease status. The chart shows what percentage of each heart disease group falls within specific age ranges.

Key Features

• Grouped Bar Chart: Compare age distributions between patients with and without heart disease
• Interactive Legend: Hover over legend items to highlight corresponding data groups
• Interactive Bars: Hover over individual bars to see exact percentage values
• Percentage Normalization: Each group (with/without heart disease) is normalized to 100%, making proportional comparisons clear

Data

The visualization uses heart disease patient data with age and disease status information.

How to Read the Chart

• Blue bars: Patients without heart disease
• Red bars: Patients with heart disease
• X-axis: Age ranges in 5-year bins (30-80 years)
• Y-axis percentages: Show what portion of each heart disease status group falls within that age range
• The percentages are calculated within each heart disease group separately, not across the entire dataset
