Data visualization is the graphical representation of data. It is the process of creating charts, graphs, and other visual aids to help people understand complex data. Data visualization helps people to interpret data quickly and easily. It is a crucial tool for data analysis, as it allows people to see patterns, trends, and outliers in the data.

What is a Waterfall Chart and How Does it Work?

A waterfall chart is a type of data visualization that shows the cumulative effect of positive and negative values. It is a way of visualizing how an initial value is affected by a series of positive or negative values. A waterfall chart is also known as a bridge chart or a cascade chart.

A waterfall chart is created by starting with a baseline value and then adding and subtracting values to show the changes over time or across categories. The bars in a waterfall chart are color-coded to show whether they represent positive or negative values. The bars start at the baseline and extend up or down depending on whether they represent a positive or negative value.

Advantages and Disadvantages of Using Excel for Waterfall Charts

Waterfall charts are a great way to visualize changes in a value over time, and Excel is a popular tool for creating these charts. There are some advantages and disadvantages to using Excel for waterfall chart.
