WebMar 4, 2024 · A graph embedding reflects all your graph’s important features. Just like a portrait encodes a three-dimensional person into two dimensions, an embedding condenses your graph so it’s simpler but still recognizable. In a graph, the structure of the data – connections between data points – is as important as nodes and their properties.
