https://toolbox.google.com/datasetsearch

https://www.kaggle.com/

https://www.data.gov/

Utilize a machine learning algorithm to create a prediction. K-nearest neighbors is recommended as an introductory algorithm. Your algorithm should read in the data set, segmenting the data with 70% used for training and 30% used for testing. Illustrate the results as output.
