Vector-Search Example: Cities

This example application starts with a pre-defined set of capital cities and their geo coordinates. It allows to search for nearest neighbors of a city (city_neighbors) or by coordinates (neighbors) as well as adding more locations (add).

python -m vectorsearch-cities
