Data structure

A single JSON file is downloaded to provide the data set. Its structure is as follows:

    'teams': {
        "67": "Uruguay",
        ...
    },
    'continents': {
        "4": "South America",
        ...
    },
    'events': {
        'world.1930': {
            'games': [...],
            'teams': [...],
            'rounds': {
                "2": "Round of 16",
            },
        },
        ...
}
