Describe the purchase value of a user

Given the following dataset, can you create a chart that describes the purchase value of a given user?

To help get you started, below is code (Python) to import the referenced dataset:

# Import libraries
%matplotlib inline
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns
# Import data
df = pd.read_csv('https://raw.githubusercontent.com/erood/interviewqs.com_code_snippets/master/Datasets/sales_data_customer_value.csv')

Note this is an example of a more open-ended question, so you're free to define and segment purchase value however you see fit, provided you call out your assumptions in the solution.
