This project documents my trip to Europe in 2023. It's made purely for sentimental and training purposes, it's not production ready code in any case.
The visualisation is done using d3.js The app draws maps of countries based on a Eurostat dataset in GeoJSON format. Data contains coordinates in 1:10M scale. The list of cities and routes between cities is loaded in csv format. Clicking on a town shows the most memorable photo. Clicking on the route shows transport details.

In the project directory, you can run:
yarn start
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
yarn test
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
