Basic Visualizations:

There are other chart options available, these will serve as a foundation for others.

Bar charts and histograms look very similar

Histograms are similar to bar charts but display numerical data instead of categorical.

Underlying data is broken into bins of equal size.

The height of each bin represents the frequency of data within the bin in the underlying dataset.

Stylized Histogram

Histogram showing transaction amount frequency

No gaps intentional gaps between bars.

Scatterplots show the relationship between two numerical variables in a dataset.

Points are arranged based on their horizontal and vertical positions.

Relationships between variables become easier to detect through a scatter plot.
