1. School of Computing Science and Engineering Course Code : CSDA4070 Course Name : Data Visualization Name of the Faculty: Mr.S.Rakesh kumar Program Name: B.Tech .( CS) INTRODUCTION TO DATA VISUALIZATION

2. Software process and Process Models Data visualization is the presentation of data in a pictorial or graphical format. The primary goal of data visualization is to communicate information clearly and efficiently via statistical graphics, plots and information graphics. Data visualization helps us to communicate our insights quickly and effectively. 2 What is Data Visualization? Program Name: B.Tech .( CS)

3. Software process and Process Models Data visualizations can be interactive, so that users analyze specific data in the chart. Data visualizations can be developed and integrated in regular websites and even mobile applications using different JavaScript frameworks Any type of data, which is represented by a visualization allows users to compare the data, generate analytic reports, understand patterns and thus helps them to take the decision. 3 What is Data Visualization? Program Name: B.Tech .( CS)

4. Software process and Process Models Effective data visualization are created by communication, data science, and design collide. Data visualizations did right key insights into complicated data sets into meaningful and natural. American statistician and Yale professor  Edward Tufte  believe useful data visualizations consist of ?complex ideas communicated with clarity, precision, and efficiency. 4 What makes Data Visualization Effective? Program Name: B.Tech .( CS)

5. Software process and Process Models 5 What makes Data Visualization Effective? Program Name: B.Tech .( CS)

6. Software process and Process Models To craft an effective data visualization, you need to start with clean data that is well-sourced and complete. After the data is ready to visualize, you need to pick the right chart. After you have decided the chart type, you need to design and customize your visualization to your liking. Simplicity is essential - you don't want to add any elements that distract from the data. 6 What makes Data Visualization Effective? Program Name: B.Tech .( CS)

7. Software process and Process Models Data visualization is important because of the processing of information in human brains. Using graphs and charts to visualize a large amount of the complex data sets is more comfortable in comparison to studying the spreadsheet and reports. Data visualization is an easy and quick way to convey concepts universally. 7 Importance of Data Visualization Program Name: B.Tech .( CS)

8. Software process and Process Models To make easier in understand and remember. To discover unknown facts, outliers, and trends. To visualize relationships and patterns quickly. To ask a better question and make better decisions. To competitive analyze. To improve insights. 8 Why Use Data Visualization? Program Name: B.Tech .( CS)

12. Software process and Process Models Here are some pros and cons to representing data visually − Pros It can be accessed quickly by a wider audience. It conveys a lot of information in a small space. It makes your report more visually appealing. Cons It can misrepresent information – if an incorrect visual representation is made. It can be distracting – if the visual data is distorted or excessively used. 12 Pro and Cons of Data Visualization Program Name: B.Tech .( CS)
