I built a world history map where every ruler links to a source

说明与用途

创建了一个静态世界历史地图，每位统治者都链接到来源，支持按时间滑动和来源验证。

问题

Most history maps show borders but not who ruled each state or source of that claim.

结果

A static, source‑verified world history map that allows users to slide through time, view rulers, and access source links for each claim.

工作流

• 1. Build map geometry and facts ahead of time.
• 2. Store data in TopoJSON files per year.
• 3. Serve a single Canvas 2D element with d3-geo inside a React island.
• 4. Use Astro pages for static content.
• 5. Enforce source requirement via fact schema rejecting entries without URL and quote.
• 6. Provide per-state pages for search queries like "who ruled France in 1960".
• 7. Offer a correction report link on each page.

证据

Every ruler, office and event links to its source. This is enforced in code, not by trust.

来源

It's fully static. There's no server. The map geometry and facts are built ahead of time, and the browser fetches one TopoJSON file per year, so moving back and forth costs little.

来源

The map is one Canvas 2D element using d3-geo, inside a single React island. The rest of the site is plain Astro pages.
