I would like to share the following COVID-19 dashboard that was created by a group of contributors led by one medical doctor during the COVID-19 crisis in Myanmar around 2020-2022. The data were extracted from the Ministry of Health and Sport (MoHS), Myanmar’s daily announcement, and worked with the Google Data Studio (current Looker Studio) at that time. The data is not updated in the meantime.

Let me discuss my preferences and dislikes, especially from the data visualization and presentation perspective. I like the following presentations.
1. It used different patterns and shapes such as bar charts, line graphs, pie charts, tables, maps, etc. which enhance our pre-attentive process.
2. It used the line graph comparison for most of the time series analysis and it is good to capture the trend over time. There are also less than 5 lines in the graph.
3. It provided some concepts of chunking to improve working memory such as separating the number digits with commas, setting the axis label as K and M for larger numbers, and separating sheets for different structures and meanings.
I feel as if there is a lot of detailed information that may be missed to capture the main point of the presented data even if the information were complete. I think the following might be needed to improve.
1. It would be better to consider the color-blind users by emphasizing the color intensity rather than the colorful bar and stacked charts.
2. There is some gap on the Axis scales (e.g. Total PUI in State/Region), very few numbers cannot be identified with the line graph and small scales would be more applicable. Avoiding complicated graphs and grid lines will be needed to keep it simple.
3. Putting different values in the same graph (e.g. test in different labs) makes us confused in the comparison and using a stacked bar chart will not align the scale between the segments.
