Canvas layout:
- Responsive width; height approximately 500px
- Simplified map of the eastern United States and Midwest showing major waterways
- Time slider at the bottom: 1800 → 1820 → 1840 → 1860
- As the slider advances, new transport routes appear on the map in different colors
Transport layers:
- 1800: Major navigable rivers only (blue lines) — Ohio, Mississippi, Hudson
- 1820: National Road (tan line) and early turnpikes
- 1825: Erie Canal added (distinct canal-blue dashed line) with tooltip showing cost/time reduction
- 1840: Early railroad lines in the Northeast (red lines)
- 1860: Full railroad network east of the Mississippi (extensive red network)
Clickable elements:
- Each transport route, when clicked, shows: route name, completion date, what it connected, and estimated cost/time reduction for shipping goods
Key annotation: Erie Canal connection from Buffalo to Albany to NYC — clicking it shows the cost calculation: shipping a ton of flour from Buffalo to NYC dropped from $100 (1817) to $10 (1830).
Color scheme:
- Rivers: dark blue
- Canals: light blue dashed
- Roads/turnpikes: tan
- Railroads: red
- Major cities: gold dots
Responsive behavior: Map scales with canvas; slider remains functional on touch screens.
Implementation: p5.js; map as simplified polygon shapes; time-slider controls layer visibility.
