--description--

Graphs are data structures representing relations between pairs of elements. These elements, called nodes, can be real-life objects, entities, points in space or others. The connections between the nodes are called the edges.

Here's a visual representation of a graph:

Rename the copper dictionary into my_graph. This will represent the graph to test your algorithm.

--hints--

You should rename your copper dictionary into my_graph.

({ test: () => assert(__userGlobals.has("my_graph")) })

Your my_graph variable should be a dictionary.

({ test: () => assert(runPython(`
    type(my_graph) is dict 
  `))
})
