Area Chart

An area chart is similar to a line chart, but the area beneath the line
is filled with colour. It emphasises the volume of data and is useful
for showing trends and magnitudes of change over time.

Pie Chart

A pie chart represents data as slices of a circle, with each slice
corresponding to a part of the whole. It’s best used for showing
relative proportions and percentages of a single data series.

Scatter Chart
A scatter chart plots individual data points on a two-dimensional

grid, helping to visualise the relationship between two variables.
It’s commonly used for correlation analysis and spotting patterns
or outliers in data.
