Mining for YouTube Sailing Channels

Recently my Dad came to me with a question about getting data on the Sailing Channels on YouTube. The number of sailing focused YouTube channels is estimated to be anywhere from 500 to about 1000 active channels. The data mining that I will perform in the following sections will only…

LIS 4317 Data Visualization: Visualizing COVID-19 Gene Sequencing Contributions

The Problem As the COVID-19 pandemic has raged, researchers have been working to track the virus and monitor its evolution. We have seen in the news a lot of discussion regarding South African, UK, and other variants of the virus. However, it is difficult to assume there is a consistent…

LIS 4317 Data Visualization: Animated Graphics

Most data visualizations are static, and while one can visualize a fair number of variables, however it can still be limited. Since we are in the 21st century, we can take advantage of our access to computer graphics and reveal more about the data by adding motion. This could be…

LIS 4317 Data Visualization: Networks

Network analysis is a very useful tool for describing complex relationships between many entities. To explore the concepts of network analysis I created 26 entities and randomly generated connections between them. To do this I wrote an R script which you can find on my GitHub here, or follow the…

LIS 4317 Data Visualization: Making a Tufte Style Visualization

Edward Tufte set out principles of design for the visualization of data. One of the big take aways from his teachings is to maximize the amount of data in a visualization, and minimize the amount of ink that is used. Often extraneous markings on a visual will just obscure the…

LIS 4317 Data Visualization: Visualizing Time Series Data

A lot of data is simply a few of variables that can be plotted in almost any way you want to. Then we have time series data, which adds a time component, and not only is it continuous, but it also defines the order of the points. Time series plots…

LIS 4370 R Programming: Visualization in R

One of the best parts of R is the ease at which visualizations of data can be created. Beyond the base library there are many packages that make visualization a powerful tool, such as lattice and ggplot2. For a while now I have been learning ggplot2 and I have become…

LIS 4317 Data Visualization: Multivariate Analysis and the 5 Principles of Design

This week was multivariate analysis. Generally useful data has more than 2 variables and to find a useful pattern, many of those variables need to be plotted together in a two dimensional space. While we could go up to 3D, that is generally not recommended for a variety of reasons,…

LIS 4317 Data Visualization: Correlation Analysis

Correlation and Regression analysis are very powerful tools when exploring data. These two forms of analysis are very useful when it comes to process improvement, take the case of a plant that converts ammonia into nitric acid. After the ammonia has been oxidized, it is passed into an absorption tower…

LIS 4317 Data Visualization: Distribution Analysis

This week was about distribution analysis. This week I made the above figure using the iris dataset in R using ggplot2. You can find the code I used to make the plot on GitHub here, or follow the link at the bottom of this post. The dataset is the famous…
