$**$This is to be done in python$**$

In an electrical engineering lab, a team is conducting experiments to measure the voltage across a resistor as a function of time. They have recorded the data in a text file named "voltage$\_$data.txt$",$ where each line contains two values separated by a comma: the time in seconds and the corresponding voltage in volts. The team needs to analyze this data to understand the behavior of the circuit.

The team wants to visualize the relationship between time and voltage by plotting a graph. They need to read the data from the file and create a plot where time is on the x$-$axis and voltage is on the y$-$axis.

Your Task:

Write a function that takes in a string for a file name and outputs the parsed data.

Plot your voltage data in the notebook.
