Module 4 - Visual Analytic Patterns

The following visualization was developed using data from the United States Department of Transportation Federal Transit Authority. The FTA supports public transportation within the United States. 

This visualization represents four measures of data, representing the Dallas-Forth Worth-Arlington, Texas metropolitan area, spanning 2014 to 2018. 

Some points of interest in this data are the number of collisions with motor vehicles in 2015 (142), and the number of collisions with persons in 2016 (13). Of the data I reviewed from the FTA dataset provided by the instructor, DFW-Arlington appeared to be an outlier with regard to these plot points. 

Both the number of collisions with motor vehicles and the number of collisions with persons declined by 2017, however the number of collisions with persons rose again in 2018.

It does not appear that vehicle revenue hours or vehicle revenue miles correlate to the alarming number of collisions with vehicles and persons, as these values have remained relatively consistent over the four year evaluation period, with the exception of a sharp decline of both values in 2018.

Module 2 - Geographic Visualizations in Tableau

Image
The following visualization (which can be interacted with here: https://tinyurl.com/publichousinginflorida) was developed based on Housing and Urban Development data for public housing developments in the United States, updated in December of 2023. The visualization represents the average household income (size of the marks) and average rent (shade of the marks) for each development in the state of Florida.  The dataset used for this visualization contains many variables, including number of occupied dwellings and vacancies, percentage of demographic groups in each development (Native American, Hispanic, female head of household with and without children), among many others.  Initially, I found it difficult to organize the visualization, because my impulse was to create pie chart markings based on occupancy. However, this proved difficult. This visualization is the result of a compromise I made with myself to represent some aspect of the data without thinking too hard about ho...

Final Project

 For the final project, I created a correlated graph a selection of data from the Orlando Police Department. View here. Between 2009 and 2024, suspect fatalities were fewer than suspects shot. Suspect fatalities were alarmingly high.

Module 7 - Distribution Analysis

Image
 For this module, we were assigned to create a visualization based on distribution analysis. I created a bar graph based on the mpg table of the mtcars dataset in R. Below is my graph: This graph shows the miles per gallon of each vehicle in the mtcars dataset. A drawback of this graph is that the vehicles are not identified on the x axis, therefore, the graph does not demonstrate the best information on distribution for this dataset.  Here is the code:  data("mtcars") head(mtcars) counts <- table(mtcars$mgp) counts2 <- table(mtcars$wt) counts View(mtcars) barplot(mtcars$mpg, main = "Miles per Gallon", xlab = "MPG", ylab = "count", col = "orange")
