4. highlight Key data: Use contrasting colors or additional elements like arrows to draw attention to the most important data points.

5. Use Labels Judiciously: Place labels close to the data they represent. Consider using interactive labels that appear on hover for a cleaner design.

6. Employ Gridlines Sparingly: Gridlines can be useful, but too many can make a chart look busy. Use them only when they add value to the data comprehension.

7. Accessible Color Schemes: Choose colors that are easily distinguishable and consider colorblind-friendly palettes.

8. Data-Ink Ratio: Maximize the data-ink ratio, which means the chart should contain more data representation and less 'non-data' ink.

9. Sort Data Logically: Arrange data in a way that makes sense for the story you're telling. For thermometer charts, you might sort data from highest to lowest to show progress.

10. Interactive Elements: If possible, add interactive elements like tooltips that provide more information when the user hovers over a part of the chart.

For example, imagine a thermometer chart designed to track a charity's fundraising progress. The goal is $1 million, and the current amount raised is $750,000. The chart should have a clear, bold marker at the $750,000 point, with a contrasting color filling up to that point from the bottom. The $1 million mark should be prominently displayed at the top, with a different color to indicate the remaining amount. Labels should be minimal, with perhaps only the $750,000 and $1 million marks labeled, and a percentage indicator showing that 75% of the goal has been reached. This design ensures that the information is quickly understood, and the viewer's attention is focused on the progress made and the goal ahead.
