This notebook visualizes citation data for scholarly articles by retrieving and processing citation counts from the OpenAlex API based on each articles's DOI.

1. Data Loading: Reads tool names and DOIs from a CSV file.
2. Data Retrieval: Fetches citation data from OpenAlex for each DOI.
3. Plotting: Creates a scatter plot with histograms showing citations by year and total citations for each tool.

Install required packages with:

pip install requests matplotlib pandas

1. Prepare CSV Input: Create a file (e.g., example.csv) with columns Name and DOI.
2. Run Notebook: The script generates and saves a visualization as a .png file.
