Data Visualizations

Data visualizations help us to see the information. They use data to show us a story.

Data Visualizations are helpful for many things. Scientists and statisticians often use them to augment their research, they tell stories with data. Data doesn’t have to be boring; it can make people laugh, cry, and even get angry.

A good example that makes people laugh is the Social Security Administration’s baby names website. This website has information about how popular specific names have been in recent years. An example that makes people upset is poverty maps, which show how much money someone needs to escape poverty. Finally, a measure that may anger you is a map of gun violence in the US, which shows how many people die every day.

Data can tell a story about anything. Data visualizations are a great way to do this. Data visualizations might be about maps, averages, and trends, or comparisons within data. The earliest example of data visualization was in 1786 when William Playfair created a line graph that showed how much money England spent on war compared to other things.

Data Visualization as we know it now wasn’t popular until recently. Before the internet and computers existed, data was hard to come by. There were not as many Data Visualizations as now. You use Data Visualizations every day. Even in the things you use every day, like checking email or doing a Google search, there is Data Visualization everywhere!

Seeing data graphically is essential to people. They are in the stuff you use every day, like checking your email or doing a Google Search. For example, when you have an email too big to print out, Gmail shows you a Data Visualization of how many pages it has. Data Visualization also helps journalists and statisticians. There are different types of Visualizations, and they include data that is in bar graphs and line graphs. The data can be understood more quickly because there is a design on top of it, so it looks prettier when seen by people who don’t know about statistics or journalism.

Data visualization is an excellent way to show data and make it easier for people to understand. It can help with decision-making and understanding patterns in the data. Visualizations are most helpful when they show numbers, text, or images.

Pictures can help you understand more. Visualizations are also helpful because they show patterns in data that someone who did not know anything about the subject would not see without any knowledge of the issue.

Even though visualizations are helpful, they might not always be the most accurate. They can be biased because of human interpretation of plotting data on a graph or which source information to use. There is also the problem of deciding what variables should get represented as z-axis vs. x-axis. These choices can affect the message that people internalize from visualizations. Sometimes people think these choices are arbitrary, so some relationships are hard to see or wholly erased because of this bias in data selection. Still, there could also be other reasons for this besides this bias in selecting data.
