Raw Data to Visualization: Top 5 data visualization techniques for beginners

Pie Chart 

The most common way of representing information and can be used in many applications. Pie charts are easy to understand, and it is helpful to the audience that requires a more detailed level of understanding. The information explained in the pie chart gives a clear picture and helps in taking proper business decisions by the executive members of the company. Data Science and Analytics use pie charts to explain the information to the audience.

Bar graph

Just like a pie chart, a Bar graph is an easy way to analyse information. In it, the data is represented in the x and y-axis. One axis represents the categories for comparison, whereas the other axis represents the value of the measurements for comparison. The analysis is done as per the height of the bar for each group. This gives a more detailed understanding of the information. Even though it is simple to understand, sometimes it can be an issue when there are too many categories.

• Gantt Chart

Gantt Chart is the most commonly used data visualisation technique in project management. The chart displays the project’s entire timeline with the details. The time interval is displayed on the horizontal axis, whereas the tasks are reflected on the vertical axis. This is highly helpful in understanding the project timeline and would give a better picture of when the project would be ready for the market. With machine learning and artificial intelligence, the company can predict the outcome of the project’s timeline.

• Heat Map  

The heat map provides information through different colours. This data visualisation technique in Data Science communicates through different colours that make the audience easier to understand. The heat map can be used by major retail store chains to understand at what time their stores get maximum footfalls. The day can be mentioned on the vertical axis, and the timings can be mentioned on the horizontal axis. By putting the colours on the boxes, the team can identify the market trends and can come up with new strategies to improve their business.

• Area Chart

The area chart is a slight variation from the line graph, where the portion beneath the line is coloured to represent the data. This chart is used to show multiple changes in over quantities in a particular period. Explaining the information is easy for the audience, and it provides information in a more detailed manner.

There are several Data Science Degrees, but pursuing Data Science from recognised universities would give the candidate an extra edge over others. The one-year Data Science for Business Excellence and Innovation course from equips the students with AI, Python, ML, Simul8, NumPy, TensorFlow, and others. This programme focus on industry exposure and provide the students with real-life business problems. It provide the students with the skill to understand and analyse the data through Data Science and Analytics. Undergoing the course from these universities would play an essential role in shaping the career of the freshers.
