How to choose correct visualization for your data?

What is Data Visualization?

Data Visualization allows you to understand your data in a better way which is easy to understand. It is all about representing your data in a visual manner through various types of charts, maps. Diagrams, etc. It can help to give proper significance to your data.

How Data Visualization work?

Data is usually in raw format. Just by watching numbers you won't understand anything. But a proper visual format will help people to extract meaning from that data and can be able to get quick information.

Data Visualizations allows you to expose patterns, trends, and correlations that may otherwise go undetected, too.

Best Practices for Data Visualizations

While determining how you will visualize your data, some of the best practices you have to keep in your mind are –

  • Choose the visual which fits best for your data and it’s purpose.
  • Ensure your visual is easily understandable and viewable.
  • Make proper context arrangement with your visual so that everyone can understand.

Questions to ask before deciding any visual for your data

Many times we don't know which visual is to be selected for what purpose. So this are some of the questions one can ask before selecting the proper visualization for their data.

Do you want to compare values?

When you want to compare the values of various columns of your data set you can use comparison chart visualizations. The can easily show the high and low trend in the data values.Some of the visualization chart you can choose are -

  • Column
  • Line
  • Mekko
  • Bar
  • Scatter
  • Pie

Do want to represent the composition of something in the data?

Many visuals can show up how a individual category make up the whole of something. For example, total sales done by sales representative.

Some of the charts favouring this category are -

  • Stacked Bar
