Sometimes real work leads to auxillary work that is needed for another purpose. That was the case in this article in which I took a deep dive into computing and visualizing population densities across the US. The results were fascinating and made a good case to share in this blog.
The VizPainter has delivered another masterpiece. This trail-blazing Tableau master used a shape file that had a time series history of the United States to win the most recent Iron Viz Competition against some amazing Tableau artists.
Introduction This is a story from today as my wife Toni and I were driving overnight from Knoxville, TN to Charleston, SC to hop on a cruise. At 2 am.or so, I looked over at her to tell her a story. This is how it went… Ken: There are about 101,000 weather monitoring stations around…
This is test 6 of a series that compares Tableau to Power BI. The purpose of this test is to compare and contrast each program’s ability to read and work with shapefiles.
This is a fun article. I created a Tableau dashboard that allows us to view 55 years of temperature data to see if global warming is impacting where we live. When you spend a little time using this tool, you will have a better appreciation of the variability of weather and the difficulty of concluding anything about global warming.
This is a summary article that contains links to the Tableau vs Power BI series I have been working on. I also include some impressions about using the software tools in real-world situations.
The vision formed 2 years ago. Many months of experimentation and testing went into completing the vision. You need to read the article to understand what I mean.
This is test 5 of a series that compares Tableau to Power BI. The purpose of this test is to see which program has a faster computational engine.
It has taken me nearly 4 years and writing over 300,000 words to create a word cloud. The data processing behind this word cloud is pretty cool, too.
This article presents a couple of techniques for drawing contour lines in Tableau. These are not simply connected polylines, but rather are simulated topographic lines represented by a series of points extracted from the mathematical surfaces used to represent topography.
I take a detailed look at maximum air temperature changes over North America. I wanted to see what has happened over my lifetime, or over the past 5 decades. The results are very interesting, at least to me.
The more I work with this data set, the more I want to know about how our climate is changing. There are so many questions I have and in this article, I have been able to answer a few of them.
Watching Gleason was the best two hours I have experienced in a long time. I became transfixed, unable to take my eyes off the movie as I fought back the emotions that upwelled in my throat.
All work and no play makes Kenny a dull boy. Every once in a while, I have to write something silly to offset all the computations and deep thinking that I do.
I had an idea about global climate changes that I wanted to investigate. When the analysis was finished, the results surprised me and have helped me begin to understand the air temperature changes that are occurring around the world.
