Class 9 : Project Interactive Data Dashboard & Presentation

 Artificial Intelligence / Data Literacy

1. What is Data Visualization?

Data Visualization means representing data in a visual form, such as charts, graphs, tables, diagrams and dashboards.

Instead of looking at a large amount of numbers, we can use a graph or chart to understand the information quickly.

Example:

Suppose the marks of five students are:

Student Marks                
                                 A 65                     
                                 B 80                     
                                 C 55                     
                                 D 90                     
                                 E 75                     

It is easier to compare these marks using a bar chart.

2. Importance of Data Visualization

Data visualization is important because it helps us:

  1. Understand data easily – Complex data becomes simple and clear.
  2. Identify patterns – We can easily notice trends and patterns.
  3. Compare data – Different categories can be compared quickly.
  4. Find trends – Charts can show whether values are increasing or decreasing.
  5. Make decisions – Visual information helps in better decision-making.
  6. Identify unusual data – Very high or very low values can be noticed easily.
  7. Communicate information – Data can be presented effectively to others.

In simple words:

“Data visualization converts data into visual information that is easy to understand and analyse.”

3. What is a Data Dashboard?

A Data Dashboard is a visual screen that displays important information using charts, graphs, tables, numbers and other visual elements.

A dashboard allows users to understand important information at a glance.

Examples of dashboards:

  • School attendance dashboard
  • Student performance dashboard
  • Sales dashboard
  • Weather dashboard
  • Sports statistics dashboard

Features of a Dashboard

A good dashboard should be:

  • Simple
  • Clear
  • Interactive
  • Easy to understand
  • Visually attractive
  • Relevant to the data

4. What is an Interactive Data Dashboard?

An Interactive Data Dashboard allows users to interact with the displayed data.

Users may be able to:

  • Select a particular class
  • Select a date
  • Filter information
  • Change the type of chart
  • View detailed information
  • Compare different categories

Example

A school dashboard could allow the user to select:

Class → Subject → Month

and then display the required student performance or attendance data.

5. What is Data Visualization with a No-Code Tool?

A No-Code Tool is a software tool that allows users to create applications, charts, dashboards or visualizations without writing programming code.

Instead of writing code, users generally use:

  • Drag and drop
  • Buttons
  • Menus
  • Templates
  • Settings
  • Data selection options

Advantages of No-Code Tools

  • Easy for beginners
  • No programming knowledge required
  • Saves time
  • Easy to modify
  • Useful for creating dashboards quickly
  • Helps students focus on data rather than coding

6. Creating a Simple Chart Using a No-Code Tool

A simple chart can be created using a no-code data visualization tool.

General Steps

Step 1: Collect the data.

Example:

Subject Marks
English 75
Hindi 82
Mathematics 90
Science 85
Computer 95

Step 2: Open a no-code visualization tool.

Step 3: Import or enter the data.

Step 4: Select the required chart type.

For example:

  • Bar Chart
  • Line Chart
  • Pie Chart

Step 5: Select the data fields.

Step 6: Customize the chart title and labels.

Step 7: Add filters or interactive features if required.

Step 8: Save or share the dashboard/chart.

7. Common Types of Charts

1. Bar Chart

Used to compare different categories.

Example: Marks in different subjects.

2. Line Chart

Used to show changes or trends over time.

Example: Monthly attendance.

3. Pie Chart

Used to show parts of a whole.

Example: Percentage of students choosing different subjects.

4. Column Chart

Similar to a bar chart but generally displays bars vertically.

5. Scatter Chart

Used to understand the relationship between two numerical values.

8. Choosing the Right Chart

Purpose Suitable Chart                
Compare categories               Bar Chart
Show changes over time               Line Chart
Show percentage/share               Pie Chart
Show relationship between two values              Scatter Chart
Compare multiple categories              Bar/Column Chart
