Note: Please only use python standard libraries covered in class lectures (i.e. json, csv etc). Please submit your solution for each problem as a standalone python file (.py) and NOT a Jupyter notebook. The TA should be able to run your program as is outside of Jupyter.
1. Develop a python class HTMLVerifier to check an HTML document for proper opening and
closing tags. In HTML, tags are defined in both opening and closing forms and must be balanced for browsers to properly render a web page. Here’s a simple example of an HTML document:
<html> <head> <title> Example </title> </head> <body> <h1>Hello, world</h1> </body> </html>
The class should have 3 methods to perform the following tasks:
• Initialize an instance with a filename and read file content, • Verify that the HTML tags are properly balanced in the document, and • Print out any unbalanced tags in the document.

2. Using the data from cities.csv, create a scatter plot of cities (as shown below) using python and matplotlib. The x-axis is the longitude of cities, the y-axis is the latitude of cities, the color represents the logarithm of city population and the size of the circles represents the total city area in square miles.
