## 1. Which chart type is most suitable for displaying monthly revenue evolution over a year in a Google Sheets dashboard?

**Answer**

A line chart is the optimal choice for visualizing continuous time-series evolution. It highlights trends, peaks, and troughs over a given period. Bar charts are better suited for categorical comparisons, pie charts for proportions of a whole, and scatter plots for correlations between two variables.

## 2. Which function allows inserting a mini-chart directly into a Google Sheets cell?

**Answer**

The SPARKLINE function creates a miniature chart inside a single cell. It is ideal for dashboards because it provides a compact visualization without taking up additional space. SPARKLINE supports several types: line, bar, column, and winloss.

## 3. What syntax should be used to create a horizontal bar sparkline in Google Sheets?

**Answer**

The correct syntax is SPARKLINE(data, {"charttype","bar"}) to get a stacked horizontal bar. The charttype parameter accepts the values line (default), bar, column, and winloss. The bar type displays a proportional horizontal bar, useful for showing progress or market share in a dashboard.
