Why this pattern works

Keep chart configuration near the visual and expose the source behind the values.

Design notes

Surface: Life expectancy
Navigation: Chart/map/table choices and data actions surround the plotted result.
Layout: The main line chart sits beside a country selector, with time controls below.
Density: Use consistent spacing within repeated information so headings, values, and secondary details remain easy to compare.
Color: White plotting surface and distinct colored series with readable labels.
Type: Use a clear type hierarchy for the page title, primary content, and supporting labels.
Pattern: Keep chart configuration near the visual and expose the source behind the values.
States: Public life-expectancy data shown as a multi-country comparison.
Don't: Do not copy brand assets or sample records. Preserve keyboard access and design empty, loading, and error states for the actual task.

## Objective
Adapt the interaction and layout patterns below to my project. Use my own content and identity. Do not reproduce logos, proprietary copy, or brand assets.

## Acceptance criteria
- Existing project conventions, design tokens, working functionality, and unrelated changes are preserved.
- Two or three reference principles clearly support the user's task; conflicts are resolved in favor of usability and the existing product.
- Reusable components and semantic HTML express the interface. Available licensed assets are used; important UI text is never rendered as a bitmap.
- Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled.
- Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported.
- Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service.

## Quality bar
Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
