Present the following data in the form of a multiple bar diagram:

\begin{tabular}{|c|c|c|}
\hline
Year & \begin{tabular}{c}
Export \\
(₹ crore)
\end{tabular} & \begin{tabular}{c}
Import \\
(₹ crore)
\end{tabular} \\
\hline
2008-09 & 5,71,779 & 8,40,506 \\
2009-10 & 6,55,864 & 10,12,312 \\
2010-11 & 8,40,755 & 13,74,436 \\
2011-12 & 8,45,534 & 13,63,736 \\
\hline
\end{tabular}



Answer :

Certainly! Let's construct a detailed step-by-step solution to represent the given data using a multiple bar diagram.

### Step 1: Understanding the Data
The data represents the exports and imports in ₹ crore across different years from 2008-09 to 2011-12. This can be tabulated as:

| Year | Exports (₹ crore) | Imports (₹ crore) |
|---------|--------------------|--------------------|
| 2008-09 | 571,779 | 840,506 |
| 2009-10 | 655,864 | 1,012,312 |
| 2010-11 | 840,755 | 1,374,436 |
| 2011-12 | 845,534 | 1,363,736 |

### Step 2: Selecting the Appropriate Tools
We need to draw a multiple bar diagram, which involves representing two sets of bars (one for exports and one for imports) side-by-side for each year. We will use the following key components:
- X-axis: Years
- Y-axis: Values of exports and imports in ₹ crore
- Two different colors for exports and imports for better visual distinction

### Step 3: Setting Up the Bar Diagram
1. Determine the positions: We will place the bars for exports and imports next to each other for each year on the X-axis.
2. Width of the bars: The width of each bar should be consistent. Let’s denote the width as `bar_width`.
3. Spacing between bars: The space should be enough to differentiate between years.

### Step 4: Plotting the Bar Diagram
Here’s a structured way to plot the diagram:

#### a) Draw the X-axis and Y-axis:
Label the X-axis with the years and label the Y-axis with "Value (₹ crore)".

#### b) Determine the range for the Y-axis:
The Y-axis should start from 0 and go slightly above the maximum value in your dataset (which is 1,374,436 for imports in 2010-11).

#### c) Draw the bars:
For each year, draw two bars, one for exports and one for imports, adjacent to each other.

#### d) Colors and Legend:
Use different colors to distinguish between exports and imports. Add a legend to identify which color represents which category.

### Example Diagram:
```
| | |
| | |
| | |
| | |
| | |
| | |
| | exports |
| exports | imports |
| imports | |
| | |
-----|---|---- |---|----|-----|
2008-09 2009-10 2010-11 2011-12
```

### Detailed Drawing Procedure:
1. Draw two bars for 2008-09, one representing ₹571,779 and another representing ₹840,506.
2. Draw two bars for 2009-10, one representing ₹655,864 and another representing ₹1,012,312.
3. Draw two bars for 2010-11, one representing ₹840,755 and another representing ₹1,374,436.
4. Draw two bars for 2011-12, one representing ₹845,534 and another representing ₹1,363,736.
5. Ensure each pair of bars (exports and imports) for the same year is adjacent but separated distinctively from other years.
6. Use appropriate colors and a legend to differentiate between exports and imports.

### Final Visualization:
By following these steps, you'll have a multiple bar diagram that accurately represents the given data, allowing for clear visual comparison between the exports and imports over the specified years.
