Module #4 Assignment

 This assignment had a primary focus on the exploration of Tableau and its functions. Using the provided data from Data.gov, I went about throwing the variables together in different combinations to see the results and how the application might express the data visually. One of the visualizations I liked was the relationship between reported city and characteristics of the incident. The characteristics I chose to visualize were the "collisions with motor vehicles", "collision with person",  "vehicle revenue hours", "vehicle revenue miles", and "ridership". I wanted to understand if location and city had any meaningful impact on these variables. The area chart below is reflective of the reported number of accidents and their respective characteristics. The chart is much larger than this image shows, and continues when scrolling up/down and to the right. 

In addition, I wanted to see if the bar graph would be better equipped to represent the relationships in the data. 

This bar graph illustrates the data in a more organized, however inefficient manner in my opinion. There are a number of Null values and instances where the number of accidents make scaling the relationship to others difficult. A benefit, however, is that there is a clear and distinct differences in the number of reported accidents between the cities, which are best reflected in bars and the use of color, width, and height of the bar graph.

I explored a lot more within Tableau to get a better understanding of the software before and after producing these designs; it is very user-friendly in a lot of ways and I think some additional practice with more data will be incredibly useful in the future.
