World Economic Forum-Global  - Risk 2021 Heni Hajdu

# data[].attributes.body
This visualization that I looked at was the "World Economic Forum - Global Risk 2021 by Harim Jung. This looks at the risks after COVID-19, in terms of the economy as a whole.

1.What problem/question does this solve/answer?
This Tableau addresses the issues that we have faced economically since the pandemic, especially in 2021. The lungs in her illustration have all of the issues within them that the pandemic has caused ecumenically - things such as poverty, unemployment, recessions, etc. She divides the lungs into two sections - greatest concern for the world on one side and most likely fallout for the world. The mock-ribs in the illustration is what holds the lungs in place - the entire global risk that we are faced with. At the bottom of the illustration, she has color coded each economic risk and estimated what present and future dangers this creates.

2.Is this really the best way to display the information?
I think this is an effective way to display the information at hand. It is very detailed and thought out and easy to follow. It is also appealing to look at and see the relation between COVID-19 and our "lungs" - the idea that we need to keep breathing even after all of the economic problems that the pandemic caused, so that we can come back from this.

3.Does everything add value?
Everything adds value because it all correlates and one section helps explain the next.

4.Is there functional interactivity?
There is no physical interactivity within the lungs - however you are able to click the image to make it bigger.

5.Are there clear labels?
The labels are clear and larger than all of the other writing. It also stands out on the navy background because the writing is mostly white.

This visualization on Tableau illustrates the history of spaceship missions being sent to Mars, featuring both successful and unsuccessful missions. This Tableau also shows the amount of spacecrafts being operated.

1. The problem that is addressed is detailing the number of unsuccessful missions that has occurred in history. While there isn't a straightforward solution, it is mentioned that every 26 months, Mars and Earth will be at their closest, which can indicate a higher chance of a successful mission.

2. I feel like this is a good way to display the information. There are a bit of notes on the side for the viewer to read in order to understand the problem and the potential solutions towards the problem.

3. As I mentioned above, I believe this data adds value. It may look simple, but each red/gray circles on the graphs can really show how impactful the data is.

4. Yes, the graph is interactable. By hovering over each circle on the first graph, you can see which country had a mission, whether it was successful or not. By looking at the second graph and hovering over the circles, you can see the exact details of the mission's name, it's intent, and the cause of it's failure (if it did fail). One example is an Orbiter that is designed to have enough fuel to be operational until 2035.

5. Because there are only two labels that is worth noting, it is clear to understand.

2. This is an excellent way to display the information. Data from four consecutive years is collected and compared between different regions of Java.
3. Everything that is displayed brings value to the problem being addressed and helps the reader to understand the problem.
4. There is functional interactivity in the way the data is being displayed. The data flows from one activity to the next. There is continuity in the display.
5. The labels are clear and easy to follow.
