1️⃣ Start with the Question: What Are You Trying to Show?

Ask yourself:
✅ Are you comparing values?
✅ Showing trends over time?
✅ Displaying parts of a whole?
✅ Understanding relationships between variables?
✅ Looking at distribution?

The purpose of your message determines the type of chart.

2️⃣ Common Chart Types and When to Use Them

1. Bar Chart

• Best for: Comparing categories
• Example: Sales by region, revenue by product
• Tip: Use horizontal bars for long category names

2. Line Chart

• Best for: Showing trends over time
• Example: Website traffic over months, stock price history
• Tip: Use multiple lines for comparison across categories

3. Pie Chart

• Best for: Showing parts of a whole
• Example: Market share by company, budget breakdown
• Tip: Avoid using too many slices (stick to 5 or fewer)

4. Scatter Plot

• Best for: Showing relationships between two numeric variables
• Example: Height vs. weight, ad spend vs. sales
• Tip: Add trendlines to highlight correlations

5. Histogram

• Best for: Showing the distribution of a single variable
• Example: Exam scores, age distribution
• Tip: Choose the right bin width to avoid clutter

6. Box Plot (Box-and-Whisker Plot)

• Best for: Showing distribution with outliers and medians
• Example: Comparing salaries across departments
• Tip: Great for statistical summaries

7. Heatmap

• Best for: Showing data density or correlation
• Example: Sales by weekday & hour, correlation matrix
• Tip: Use color scales wisely—too many shades can overwhelm
