DATA PROCESSING: The data is a comma-separated-value file compressed via bzip2 algorithm to reduce its size. Hence, the first step is to read the data into a data frame and display a summary of the information.
ANALYSIS: The following plot shows top dangerous weather event types. This graph reflects that the tornado was the main cause of death during those 61 years; there were more than 5,000 deaths and more than 10,000 injuries during that period in US.
