In the teaching slides for 01-graphical-elements, add example chart types that use one or more of the visual properties discussed in the better/worse section "Better visual representations."

In the 2022-07-25 trial run, this episode ran over the estimate by 10 minutes - 40 minutes total including exercises.

Feedback from first trial run says that the x axis on this chart is confusing. Find a way to revise the chart to show both avg. temp and month of the year.

After second trial run, update timing in 02-Identify-and-Interpret-the-message.md and 03-communicating-the-message.md

Might other software for producing visualizations be considered?
Examples include:

• LibreOffice
• OnlyOffice
• Binder

Don't need to keep the Markdown template for episodes. Alternatively, turn it into the intro/motivation for the lesson.

When attempting to insert a new x-axis in Lesson 4, data gets imported as a new data series every time. This seems to be a bug in google docs. It would be better to restructure the Lesson at this point to avoid that bug. Recommended fix would be to change the lesson to have student import their x-axis data as a data series first and then walk through how to set that data series as an x-axis.

In a Markdown table, the text alignment is not rendering correctly on the site. The first column is always either right-aligned or centered, but never left-aligned, no matter what Markdown syntax is used to force the alignment.
The same .md file is rendered correctly by GitHub on the repository side; thinking this might be a Workbench bug.

Make to circle back to data types when discussing each graph in episode #3

Path is learners/setup.md under Software Setup

Path is learners/setup.md

Find terms we know we are mixing/matching and edit to use the term we've agreed on going forward:

• chart / graph / visualization - use chart
• communicate / message - use message

The list of visual properties in Challenge 2.1 doesn't match the same list on the slide. Address this by either:

• putting the same list on the slide as is in the challenge
• making a separate slide for the challenge

Add a citation in learners/setup.md for the dataset we are using. Link to the Dryad page is https://datadryad.org/stash/dataset/doi:10.5061%2Fdryad.s0d20

Schedule work time to work on the lesson. On the calendar already:

• Thursday, 6/23 1-3 pm CDT
• Thursday, 6/30 Carpentries Lesson Development Co-working time options (all CDT):
  • 9-11 am
  • 3-5 pm
  • 5-7 pm

In the 2022-07-25 trial run, learners offered different answers to challenge 2.2 than the "correct" answers included in the solution.

Update the instructions on this challenge to indicate that learners should rank the charts from better to worse based on what they just learned about which visual properties are better and worse for accurate perception.

Optionally add note that learners' own opinions about which chart is better may be different from the "correct" answer depending on how much experience they've had with charts.

All of this data is made up and in Excel, along with the charts. Not sure what the best approach is for GitHub, but the images can't be updated without the source data and chart.

Looks like the path to download the data in Instructor VIew is https://jbkieffer.github.io/intro-data-viz/instructor/data/canids.tsv - which doesn't exist. Suspect it's a consequence of hosting the data in the repository.

This might be solved with a different approach to the data download link; perhaps park the link in learner/setup.md?
