TypeError: Object of type int64 is not JSON serializable

[bmaz]

Oops I used pandas

import pandas as pd

table = pd.read_csv(file)

graph = table_to_bipartite_graph(
    table, 
    first_part_col="nom", 
    second_part_col="mentions", 
    first_part_data=["sexe", "twitter_description", "twitter_followers"]
)
Sigma(graph, node_color="part", node_size="twitter_followers").to_html("graph.html")

I propose to cast int64 as serializable JSON ints if they don't exceed 53 bits. Else, we should raise an error explaining those values should be cast to string instead.
