YC Demo Day: I mapped out every YC company on an interactive world map

Since it’s YC Demo Day, I thought it would be fun to re-share a project I built: a world map of all YC companies.

The map lets you:

• Explore where YC founders are building across the globe

• Filter by batch

• Click into companies directly

Would love your feedback.

ps.: for those who've seen this before, I fixed all companies' locations.

Nice. I would advise merging the countries 'México' and 'Mexico'. They return different sets of companies.

I found a bug --- when I click on a circle with a number, the map correctly zooms in to the area and shows the companies, but when I zoom out, I am unable to load companies outside of that area, e.g. I clicked on SLC and saw the companies there, but I see no companies outside of SLC when I zoom out.
