How to implement custom plotly bubble chart

Hey @Youp

this code

import plotly.graph_objects as go
import plotly.express as px 
import pandas as pd

data = {'x': [1.5, 1.6, -1.2],
        'y': [21, 16, 46],
        'circle-size': [10, 5, 6],
        'circle-color': ["red","blue","green"]
        }
# Create DataFrame
df = pd.DataFrame(data)
fig = px.scatter(df, x="x", y="y", color="circle-color",
                 size='circle-size')
fig.show()

creates

As for your second question, what do you want to do? Have a different background color in each axis sector? If so, you could create shapes.
