?? Quick Recap

In Day 6, we explored data modeling basics – understanding tables, relationships, and building a data model. Today, we’re taking the next step: creating your first visual.

?? Why Visualizations Matter

Visualizations are the heart of Power BI. They transform raw data into meaningful insights, making it easier to understand trends, patterns, and outliers. Whether it’s a bar chart, line chart, or pie chart, visuals help you tell a compelling data story.

?? Building a Simple Bar Chart

Let’s create a bar chart step by step:

1. Load Your Data

• Open Power BI Desktop and load your dataset (e.g., sales data).
• Ensure your data is clean and ready for analysis.

2. Select the Bar Chart Visual

• In the Visualizations pane, click on the bar chart icon.
• A blank bar chart will appear on the report canvas.

3. Add Data to the Chart

• Drag a categorical field (e.g., Product Category) to the X-axis.
• Drag a numerical field (e.g., Sales Amount) to the Y-axis.

4. Customize Your Chart

• Use the Format pane to customize colors, labels, and titles.
• Add a title like “Sales by Product Category” to make your chart clear and informative.

?? Pro Tip

Sort Your Data: Click the sort icon in the visual to sort bars by ascending or descending order. This makes it easier to spot trends and outliers.
