Electric Vehicle Population Data

This dataset provides information on the number and types of electric vehicles registered in the State of Washington. It includes details such as the make, model, year, and electric range of the vehicles. 

Something interesting about this dataset is that it could be used to reveal trends in electric vehicle adoption in a particular region. This could allow analysts to investigate how the popularity of certain models has changed over recent years.
