Module # 8 Correlation Analysis and ggplot2

 



What I noticed is that the dark blue boxes show a strong negative correlation, and the very light blue boxes show a strong positive correlation. I noticed that mpg has a strong negative relationship with weight, horsepower, and cylinders, which is shown by the darker shaded boxes. I also saw a strong positive relationship between displacement, horsepower, and cylinders, showing that bigger engines usually have more power.

The grid layout made it easy to compare all the variables at once. Each square showed a different relationship, and the colors made it simple to see which ones were strong or weak. It helped me notice patterns faster without the chart looking messy or hard to read.

Few’s recommendations helped because they made me understand that keeping the visual clean and simple with clear labels and colors makes it less chaotic and easier to understand.

Final Project: Visual Analytics

Image
For this project, I was not sure which dataset to use, so I went through the R built-in datasets and chose the ToothGrowth dataset. It was easy to work with, and it has enough observations for me to make different visuals and compare patterns. The main question I wanted to go over in this project was how different supplement types and dose amounts affect tooth length. I also wanted to see if there was a big difference when increasing the doses. My goal was to understand the patterns in the ToothGrowth dataset. Related works I looked back on was the mtcars dataset we worked on for some of the assignments. We used boxplots, scatterplots, and other visuals to compare variables, which helped me decide which graphs to use for this project and gave me ideas for the visuals I made for the ToothGrowth dataset. For my solution, I used RStudio to make all the visuals and used a dataset that was already built into R. I created three graphs that helped me explore the dataset further. The first gra...

Module #9: Visualizing Multivariate Data with ggplot2 & Corrgram

Image
  I used the Iris, which has many flowers and includes details on sepal length and width, as well as petal length and width. I used this dataset because it measures different flower types, such as setosa, versicolor, and virginica.  My visualization measures sepal length and compares it across the three species of iris flowers. The boxplot shows that setosa has the smallest sepal length, virginica has the largest, and versicolor is in between. This visualization helps tell the differences and similarities.  Yes, the boxplot is a multivariate visualization because it compares sepal length across three species. Making it easy to compare them side by side.  In my boxplot, I used alignment by keeping everything easy to read and compare. I also used contrast by using a gray background with red boxes so the boxplots would stand out, and I used balance by spacing the boxplots evenly so the chart looks neat and easier to read and understand.

Assignment # 12 using Python with netwokxx and plotnine

Image
  The code ran successfully. It was difficult at first because I don’t usually use Python, so I had to install it and figure out how it works. At first, I was typing the commands into the Python shell and the code didn’t run. After doing some research, I realized I needed to use Command Prompt instead to install everything correctly. Once I ran the code there, it worked and generated the ggplot output confirming the graph was created. I personally would not use this method because it was confusing to set up and the graph did not show up in the command prompt.
