Module 11: Dot-Dash Plot in lattice

 

    For this week’s visualization, I recreated the dot-dash plot using the lattice package in R. This type of plot was mentioned in Dr. Piwek’s discussion of Edward Tufte’s design principles, which emphasize simplicity and data-focused graphics. My version uses the built-in mtcars dataset, plotting miles per gallon (mpg) against car weight (wt). Each point represents a car, while the small dashes (created with panel.rug()) along the x- and y-axes show the data distribution without needing full histograms.

    The minimalist style follows Tufte’s “data-ink ratio” idea, using only the essential visual elements to highlight the relationship between variables. The clean background and limited color make it easy to focus on the pattern of the points rather than decorative elements. I like this design because it feels both simple and professional, showing how much you can communicate visually with very little clutter.

Student Loan Program Trends in the United States (2007–2025)

Image
Written Report      This project examines how federal student loan programs in the United States have changed over time, with a focus on borrowing amounts, the number of student recipients, and the growing cost burden on individual borrowers. Although student debt is often discussed as a single issue, most people are not aware that federal loans come from different programs, each with its own history and trends. The goal of this analysis is to understand which programs are expanding, which are disappearing, and whether students today are receiving more borrowed dollars per person than they did in the past.      The idea for this project was influenced by several existing visual resources, including the Federal Student Aid dashboard, DataUSA’s educational finance reports, and journalist-designed college affordability graphics. These examples revealed how powerful visual storytelling can be in making complex financial data easier to understand. However, man...

My Geographic Map of Florida COVID-19 Cases by ZIP Code

Image
     For this week’s assignment, I was instructed to find a dataset and create a visual using Tableau. I selected the Florida COVID-19 Cases by ZIP Code (April 28, 2021) dataset from the University of South Florida Libraries’ Digital Heritage and Humanities Collection, originally downloaded from the Florida Department of Health ArcGIS Data Portal. Using this data, I wanted to examine how COVID-19 cases were distributed across Florida ZIP codes during the s pring of 2021. After importing the dataset into Tableau, I generated this geographical map using a blue color scale , since it provided the clearest contrast.      On the map, ZIP codes shaded in darker blue represent higher case counts, while lighter areas represent lower counts. Unsurprisingly, South Florida ZIP codes (especially in Miami-Dade and Broward counties) had the highest reported numbers. Central Florida areas around Orlando also showed clusters of elevated case counts. What stood out most w...

Spotting Differences in R: Comparing Fuel Efficiency by Cylinder Count

Image
  For this assignment, I used RStudio and the built-in mtcars dataset to explore differences in average miles per gallon (MPG) across cars with different numbers of cylinders. Using ggplot2 , I created a simple bar chart that displays the mean MPG for 4-, 6-, and 8-cylinder cars. The chart clearly shows that 4-cylinder cars achieve the highest average fuel efficiency , followed by 6-cylinder, and then 8-cylinder vehicles with the lowest MPG. This visualization directly supports a spotting differences task, it makes the contrasts between groups immediately visible through bar height comparisons along a shared baseline. From a design perspective, I applied a minimal theme and used a clear title and axis labels to keep attention on the comparison itself. This aligns with Stephen Few’s  principle of simplifying visuals so that viewers can detect differences quickly and accurately. Likewise, Yau  emphasizes using straightforward encodings, like length along a common scale...
