Free Data Sources and Free Data Sets to use in 2021

Every good data visualization starts with good accurate data. I started in data visualization as a web analyst and I didn’t know anything different than data related to website performance. I wanted to work on improving my data visualization skills but I had no idea how to find data. I only had access to data from Google Analytics for different websites. As I worked my way through mastering data visualization and data storytelling I compiled a list of free publicly available data sources and data sets and I want to share with all of you intrested in practicing data visualization and data science.
