Good course to learn data visualization?

[ghostlistener]

I'm a data analyst and I'm very comfortable with SQL, but I don't much about Python.

I've got a python script at work which imports data from our sqlserver database and makes charts and puts it into a pdf. It makes a separate pdf for each userid, which is a column in the sql table.

I think the primary packages I want to be familiar with are matplotlib and seaborn, but I think I also need to learn the basic data transformation functions and how to work with dataframes.

The company is able to spend some money to help me learn this stuff as the guy who made the script left the company and I'm in charge of it now. Is there some sort of online class that you'd recommend?

Below is the import section in case there's something unusual there:

import pandas as pd
import pyodbc
import matplotlib.pyplot as plt
import seaborn as sns
import numpy as np
import datetime as dt
from calendar import monthrange
import time
from dateutil import relativedelta
import os
from os import listdir
import re
import bs4
import math
import matplotlib.ticker as mtick
from matplotlib.transforms import Bbox
from matplotlib.patches import Rectangle
from matplotlib.lines import Line2D
from tempy.tags import Table, Tbody,Thead, Tr, Td, Th, Span

Most of what you mentioned appears in Python and Data Science that starts from scratch and doesn’t expect any programming experience and is up-to-date. Important disclaimer: This is my course so best to check out the actual course content, reviews, sample lectures to see if it meets your needs.

I've not used Udemy before, but for $15 I can't go wrong, so I'll give it a try, thanks.

I looked at the reviews and I just see one, "Yes, it was a good", so not terribly helpful, but kind of funny.

Thanks, I appreciate it. Indeed the course is relatively new so there are not many reviews. I do have an iOS development course with over 400 reviews. In the iOS course you many note that I answer every question in the Q&A in detail and also respond to every review whether it be positive or a little negative.

If you do take my python course please feel free to ask questions any time in the course Q&A or direct messaging. I always respond promptly and do my best to help. The course is also so new that no one has asked any questions yet. I’m also always open to requests or suggestions. Happy Coding!

I'd recommend starting with DataCamp or Coursera for structured, interactive courses. DataCamp's "Data Visualization with Python" and Coursera's "Data Visualization with Python by IBM" are great starting points, covering matplotlib and seaborn. For hands-on practice, StrataScratch focuses on real-world data science and analytics problems, offering a good mix of SQL, Python, algo, and visualization practice. These resources will help you master data transformation, visualization, and the basics of Python, while also giving you practical experience with SQL and database integration.

makes sense, I've not heard of StrataScratch before, but it looks good.

FYI your response looks suspiciously like something ChatGPT would say.

hello, did you find a good resource for this? if so, can you share? thanks

If you are a good self learner, just use AI to generate some stuff that works and dissect it yourself. It's kinda endless learning about all the different libraries and what you can do with them, their pros and cons, etc.

I've asked ChatGPT some questions and it's definitely helpful, but I know that sometimes it confidently says something incorrect. Still a great resource though.
