SF Historical Markers\n\nAn interactive map of **749 historical markers** across San Francisco, sourced from the [Historical Marker Database (HMDB)](https://www.hmdb.org/).\n\nBuilt with [Leaflet.js](https://leafletjs.com/) and OpenStreetMap — no frameworks, no build step, just a single HTML file and a JSON dataset.\n\n![Dark-themed split-pane interface with a sidebar listing markers and an interactive map on the right](https://via.placeholder.com/900x400/0f172a/93c5fd?text=SF+Historical+Markers+Map)\n\n---\n\n## Features\n\n- 🗺️ **Interactive map** — click any pin to see the marker's title, address, year erected, and a link to its HMDB entry\n- 🔍 **Full-text search** — filters by title, subtitle, address, and erected-by text in real time\n- 📅 **Year filter** — narrow down markers by the year they were erected\n- ⚠️ **Missing filter** — show only markers that have been reported missing (or exclude them)\n- 📋 **Sidebar list** — click a card to fly the map to that marker and open its popup\n- 🌙 **Dark UI** — easy on the eyes, grid layout with sidebar + full-height map\n\n---\n\n## Data\n\n`hmdb_sf_markers.json` — 749 markers with the following fields:\n\n| Field | Description |\n|---|---|\n| `id` / `markerNo` | HMDB identifiers |\n| `title` / `subtitle` | Marker text |\n| `yearErected` | Year the marker was installed |\n| `erectedBy` | Organization that erected the marker |\n| `coordinates` | `{ lat, lng }` |\n| `address` | Street, city, section, county, postal code, location text |\n| `missing` | Whether the marker has been reported missing |\n| `link` | Direct URL to the HMDB entry |\n\n---\n\n## Usage\n\nBecause the page loads `hmdb_sf_markers.json` via `fetch()`, you need to serve it from a local web server (opening `index.html` directly as a `file://` URL will be blocked by the browser).\n\n**Python (quickest):**\n```bash\npython3 -m http.server 8080\n```\nThen open [http://localhost:8080](http://localhost:8080).\n\n**Node (npx):**\n```bash\nnpx serve .\n```\n\n---\n\n## Tech Stack\n\n| Layer | Tool |\n|---|---|\n| Map | [Leaflet 1.9.4](https://leafletjs.com/) |\n| Tiles | [OpenStreetMap](https://www.openstreetmap.org/) |\n| Data | [HMDB](https://www.hmdb.org/) |\n| Runtime | Vanilla JS (ES2020+), CSS Grid |\n\n---\n\n## License\n\nData © [Historical Marker Database](https://www.hmdb.org/) contributors.
