A lot of presentations are focused on data and numbers. Sounds boring, right? Apart from essential business presentation phrases, charts, graphs, and diagrams can also help you draw and keep the attention of your listeners. Add them to your presentation, and you will have a profound evidence-based work.

When it comes to presenting and explaining data charts, graphs, and diagrams, you should help people understand and memorize at least the main points from them. As to the use cases,  diagrams and other visuals perfectly fit for describing trends, making a comparison or showing relationships between two or more items. In other words, you take your data and give it a visual comprehensible form.

What is better to choose

There are so many different types of charts, diagrams, and graphs that it becomes difficult to choose the right one. The chart options in your spreadsheet program can also greatly puzzle.

When should you use a flow chart? Can you apply a diagram to presenting a trend? Is a bar chart useful for showing sales data? To figure out what to select, you must have a good understanding of the specific features of each type.

The rest of this article will show examples of different types of presentation visuals and explain in detail how to describe charts and diagrams.

Graphs, Charts & Diagrams

Data can be represented in many ways. The 4 main types of graphs are a bar graph or bar chart, line graph, pie chart, and diagram.

Bar graphs are used to show relationships between different data series that are independent of each other. In this case, the height or length of the bar indicates the measured value or frequency. Below, you can see the example of a bar graph which is the most widespread visual for presenting statistical data.

Line graphs represent how data has changed over time. This type of charts is especially useful when you want to demonstrate trends or numbers that are connected. For example, how sales vary within one year. In this case, financial vocabulary will come in handy. Besides, line graphs can show dependencies between two objects during a particular period.

Pie charts are designed to visualize how a whole is divided into various parts. Each segment of the pie is a particular category within the total data set. In this way, it represents a percentage distribution.

Diagram is a plan, drawing, or outline created to illustrate how separate parts work and overlap at the connecting points.

How to begin a description

Once you create a fascinating graph for your presentation, it is time to know how to describe graphs, charts, and diagrams. To catch your audience’s attention from the very beginning, you can use the following phrases for introduction:

• Let me show you this bar graph…
• Let’s turn to this diagram…
• I’d like you to look at this map…

How to describe bar graphs

Bar graphs transform the data into separate bars or columns. Generally, this type of visuals have categories on the x-axis and the numbers on the y-axis. So, you can compare statistical data between different groups.

The bar graphs show which category is the largest and which is the smallest one. Each group should be independent so that the changes in one do not influence others. The bars or columns can be drawn either vertically or horizontally, as it doesn’t make any difference.
