Start with Data Visualization

Introduction:

In today’s world, volume of data is increasing rapidly in each and every area. To analysis this data and conclude some decision, we definitely need to visualize those information. Here it comes the concept of Data Visualization.

Type of Presentation:

During analysis of any data set, we need to keep in mind some points.  For example,

  1. How many variables need to captured in a single chart
  2. Whether the chart will be based on categorical data or time series data
  3. What will be the data limitation?
  4. If we are creating dashboard, then what will be the story line of that, how many charts will be included. etc.

To answer all the above questions, we can identify that there is 4 type of presentation.

  1. Comparison
  2. Composition
  3. Distribution
  4. Relationship
