Matplotlib Pandas: visualization of 3 columns (Python)

Matplotlib Pandas: visualization of 3 columns (Python)

Problem Description:

I have parsed data and created a small data frame that looks like this:

And I want my graph to look like this:

Let me know if this is possible to be done and if it is not, give me some suggestions on what do you think best representation of this data would be!

And when I try running the basic bar chart it gives me an error

fig = plt.figure(figsize = (10, 5))
p = max_sales_by_state["State or Province"]
s = max_sales_by_state["Sales"]

plt.bar(p, s, color =['maroon', 'aqua', 'magenta', 'green'])
 
plt.xlabel("State / Province")
plt.ylabel("Sales")
plt.title("Sales per state")
plt.show()

I get an error KeyError: ‘State or Province’

You can try the following:

import pandas as pd
import matplotlib.pyplot as plt

data={
        'Region':['Central', 'East', 'South', 'West'],
        'States':['Illinois', 'New York', 'Florida', 'California'],
        'Sales':[98971.25, 223930.48, 87651.11, 288310.61],
    }
df = pd.DataFrame(data)
df = df.sort_values('Sales', ascending=False)

fig, ax = plt.subplots()
ax.bar(df['Region'], df['Sales'], label=df['States'], color=['red', 'green', 'blue', 'grey'])
for bar, state in zip(ax.patches, df['States']):
    ax.text(bar.get_x()+bar.get_width()/2, 10000, state, rotation=90, color = 'black', ha = 'center', va = 'bottom')

resulting in :
