What is a chart in spreadsheet? Briefly explain various types of charts.

A chart in Excel is a visual graph of worksheet numbers, making trends and comparisons instantly clear for reports. Select data → Insert → Charts.

Types:

1. Column/Bar — Compares values across categories. Example: monthly FIR counts per station. Best for exam-result comparison.
2. Line — Shows trend over time. Example: internet users 2075–2080 rising steadily.
3. Pie/Doughnut — Shows share of whole (100%). Example: budget split — salary 50%, fuel 30%, other 20%. Use few slices only.
4. Area — Like line but filled, emphasizes volume over time.
5. X-Y Scatter — Relationship between two variables. Example: study hours vs marks.

Choose by question: comparison = column, trend = line, share = pie. Add title, axis labels and data labels for full marks.
