In countless modern industries, data is an invaluable tool. You’ve likely even used a data visualization tool or two. But what is data visualization, how is it used, and what are its benefits?
Data visualization is the practice of displaying data in a graphical or tabular form. The purpose of data visualization is to help us understand the data by seeing it in a way that is easy to interpret.
Ways to Visualize Data
There are many different ways to visualize data. Some of the most common are:
A bar chart is a graph that uses bars to compare different values. The bars can be either horizontal or vertical, and they are typically displayed in a chart. The height of the bar corresponds to the value of the data point, and the width of the bar corresponds to the percentage of the total.
A line graph is a graphical representation of data in the form of points connected by straight lines. The data can be quantitative (e.g. time, temperature, weight) or qualitative (e.g. sex, race, nationality). Line graphs are useful for displaying trends over time or space.
A pie chart, or pie graph, is a circular chart divided into sections, or “slices,” to show how much of a whole is taken up by each part. Pie charts are used in many fields, including business, science, and statistics.
A scatter plot is a graph in which two variables are plotted against each other. The data is displayed as points, and the position of the points corresponds to the values of the two variables. The scatter plot enables you to see the relationship between the two variables.
Each type of graph has its own strengths and weaknesses. The best type of graph to use depends on the type of data you are trying to visualize and the message you want to send.
For example, if you want to compare the size of different data sets, you might want to use a bar chart. If you want to track a variable over time, you might want to use a line graph. If you want to compare different values, you might want to use a pie chart. And if you want to see how two variables are related, you might want to use a scatter plot.
The Importance of Data Visualization
There’s no question that data is important—but what do you do with all that data? More and more, businesses are turning to data visualization to help them make sense of their data and find trends. Data visualization takes all of your data and turns it into easy-to-understand charts, graphs, and other visuals.
Why is data visualization so important? There are a few key reasons:
Data visualization makes it easy to see trends.
If you have a lot of data, it can be difficult to see any patterns. Data visualization makes it easy to see trends and correlations that might not be obvious when you’re looking at a spreadsheet of numbers.
Data visualization is a great way to share information.
When you have data that’s easy to understand, you can share it with your team or clients in a way that makes sense to them. Data visualization is an effective way to show off your data and make your case.
Data visualization is a great way to learn.
If you’re trying to learn more about your data, data visualization is a fantastic way to do it. With data visualization, you can quickly see patterns and trends that you might not have noticed before.
Data visualization is fun!
Okay, this one is subjective, but data visualization can be a lot of fun. It’s interesting to see how your data changes over time and to see how it correlates with other data.Data visualization is an important tool for businesses of all sizes. If you’re not already using data visualization, it’s time to start.
