Hello,

I have a question - I have differences calculated between game genres. The difference is a positive float number, the bigger the number, the greater the difference there is between the two genres.

I want to visualise differences and I have the following code:

import json
import networkx as nx
import matplotlib.pyplot as plt

with open('genres_weights.json', 'r') as file:
    data = json.load(file)

G = nx.Graph()
max_diff = max(item['difference'] for item in data) if data else 1.0

for item in data:
    node1, node2 = item['weightsPair']
    difference = item['difference']
    weight = item['difference'] + 0.25

    G.add_edge(node1, node2, weight=weight, original_diff=difference)

plt.figure(figsize=(40, 20))
pos = nx.kamada_kawai_layout(G, weight='weight')

nx.draw_networkx_nodes(G, pos, node_size=2000, node_color='#2b83ba', alpha=0.9)

nx.draw_networkx_labels(G, pos, font_size=7, font_family='sans-serif')

plt.show()

that gives the following result for my data:

A lot of things look great, and overall graph represents data correctly (I guess). But there is the thing - in the bottom left part of the graph there are two bubbles: “immersive sim” and “rhythm”. Those two genres appear to be very similar (as some other pairs of games that are very similar and have a very low number for difference), but in reality, they are not - they have a difference of 9, which is a lot (the maximum difference between genres is around 14), so I expect them to be on the different side of the graph and not nearly together.

I’m not sure where the problem is. Can someone please help me?
