Use \"Royal\" style fonts for pomp and ceremony in the title and pop-ups. Choose from available Google Fonts.\n\n# Map\nKeep the map focused on the Netherlands only. Don't let the map be zoomed out past the Netherlands. Users may zoom in 3 or four times the initial zoom. If a visit was outside of the current Netherlands, please omit it.\n\nFind a nice base, simple gray-scale base map and give it an orange tint.\n\n# Symbology\nFor each visit, please a royal crown symbol. Purple for Beatrix and Dark Blue for the guy. If the symbols overlap a little bit, offset them a little so both are selectable at once.\n\n# Title\n- \"Happy Koningsdag, Netherlands!\"\n\n## Subtitle\n- \"A map of historic photo-op visits by Queen and King\"\n\nWhen users click on a visit, the person and place visited, with the year should show up in a pop-up.\n\nIn the attribution modal please include:\n- Original data source: https://en.wikipedia.org/wiki/Koningsdag\n- Data created using Perplexity Pro.\n- Map: Web Map GPT (link to map)\n- Provenance file: link to provenance file\n- Map Tiles: {provider}\n- APIs: {list APIs}\n- Part of the 365 Days of Maps Campaign.
