#WatchMeViz: Can viral infections be cured with antibiotics?

No comments
I'm really surprised, though maybe I shouldn't be, about the results from a poll of 1206 Americans by KFF. They asked a simple question: 

"Can viral infections usually be cured by antibiotcs, or not? Or do you not know enough to say?"

According to the results, women know better than men, as do adults with higher incomes and higher levels of education.

I took on this data set for Watch Me Viz for Makeover Monday week 14. Check out my final viz here. There's an image below the video.

#MakeoverMonday 2024 Week 11 - Housing Vacancies in America

No comments
This week I decided to turn Makeover Monday into a Workout Wednesday of sorts. I wanted to try a technique I haven't used in a while...showing elements on either side of a rank and filtering out the rest.

Want to give it  a try? Get the data here.

Requirements:
  1. Size - 1000x475
  2. Max 4 containers; no tiled containers allowed
  3. Filter out Alaska, Hawaii and Puerto Rico
  4. Clicking on a MSA in the map highlights the MSA in the map and bar chart and changes the MSAs that are displayed in the bar chart
  5. The bar chart shows the rank of the MSA for the metric selected.
  6. There should always be 11 bars (though I didn't test the lowest rank).
  7. The label on the end of the bar and in the map reflect the formatting of the measure selected (i.e., either whole numbers or a percentage to one decimaal).
  8. Include an option to change the measure and to change the number of MSAs on the map.
  9. Create a mobile view
  10. NO LODS!

Have fun!

Visualizing Time Series Data in Tableau

No comments

Last night I was invited to speak at the Chicago Tableau User Group about visualizing time series data. Other than spatial data, time series data is my favorite to visualize. 

There seem to be endless methods for making time series data useful for analysis. Check out this video for 60ish ways to visualize time.

I had a 20 minute slot to present and, of course, I ran over time. I seem to do this with every session I run lately. Be it training for Next-Level Tableau, presenting at events, or running a livestream, I get into a groove and don't want to stop.

I was able to create 14 vizzes in 20+ minutes. I added an extra in this workbook to make the dashboard format nicely.

Have fun!
