First, here's an open secret - adding a graph to your answer in economics gets you more marks - plain and simple! So, that is why graphs seem to follow you everywhere you go since you started studying economics. That is because economics can be very wordy, and it is essential for graphs in economics to show you things in visual format! (a picture speaks a thousand words, or whatever they say). So, let's find out all about the graphs in economics.

Here you are, you have a vague idea of what an economics graph looks like, but when asked, what are you going to say? Generally speaking, a graph is a visual illustration of numerical information. While simple numbers may be easy to present in numerical format, numbers that are relative to other numbers may be confusing, and graphs help you visualize these relationships. Graphs in economics serve this purpose. It takes very confusing numbers and presents them in the form of patterns. These patterns retain the complete information, yet, they appear summarized, making graphs ideal for simplifying (complicated) things.
An economics graph is a visual illustration of numerical data in economics.
Economists plot graphs on two axes: the vertical axis, also known as the y-axis, and the horizontal axis, also known as the x-axis. Look at figure 1.

The importance of graphs in economics is this; they simplify numerical data to improve readability.
Economics graphs simplify numerical data for easier readability without losing detail.
However, economics graphs are also important because they illustrate the relationships and connections between different variables or concepts in economics. For instance, graphs are important in visualizing the relationship between the price and the quantity of a good. What would take several lines of text to understand can take an instant to understand with the help of a graph.
A well-plotted graph should be able to show the full picture and not just a summary of it.
Let's make it clear from the start that you'll most likely be encountering line graphs a majority of the time. However, there are three main types of economics graphs, and they include line, bar, and pie graphs. We'll discuss them here.
The first and most used type of economics graph is the line graph. Line graphs show the relationship between two economic variables plotted on the horizontal and vertical axes. Let's look at the following example.
Kent buys 3 apples for $5 per apple and 5 apples for $2 per apple.
From the simple example above, we can see that the price of apples and the quantity of apples are interacting with each other. So, how do we show you a picture of this? We use the line graph as shown in Figure 2.
Line graphs show relationships between variables in economics.
To interpret a graph, we look at each point and trace its corresponding points on the vertical and horizontal axes.
Figure 2. Line Graph, StudySmarter Originals
Figure 2 shows that the quantity increases when the price decreases. This indicates that Kent is willing to buy more apples when the price goes down. This is a demand curve showing the negative relationship between price and quantity!
Just a pro tip. If it is about price or cost, then keep in mind that money is on the vertical axis, and whatever accompanies the money is on the horizontal axis. Also, we read graphs from the left to the right. So, in this example, the line slopes downward from the left to the right.
The second type of economics graph is the bar graph. This one just compares quantities. For example, you would see the numbers, 1013, 1035, and 1033, representing the number of fish in ponds A, B, and C respectively. The bar graph helps you get the whole picture and shows the differences between the three ponds based on the height of the bars. Look at Figure 3.
Bar graphs compare quantities using the height of the bars.

The third type of economics graph is the pie graph, which is also used to compare quantities. However, this compares quantities as fractions of a single whole.
Pie graphs compare quantities as fractions of a single whole or total.
Let's say there is a small market with 5 blue shirt sellers, 3 green shirt sellers, and 2 pink shirt sellers, making a total of 10 shirt sellers. Look at Figure 4 as an example of a pie graph.

Undoubtedly, graphs are essential in economics. However, what exactly do economists use these graphs for? Surely, they don't just represent fancy designs. Below we will discuss some uses of economics graphs.

While there are many graphs you will encounter as you make progress in your economics studies, let's look at three examples of some economics graphs. These are the product market graph, the land market graph, and the capital market graph.
Example 1. the product market graph showing demand and supply. Look at Figure 8.
Example 2. Land market graph showing the supply of land. Look at Figure 9.

Example 3. Capital market graph showing the demand for capital. Look at Figure 10.

These are just examples to show you what graphs generally look like in economics. You have reached the end of this article already! You should read our articles on Market for Capital and Land Market to find out more about these examples!

What is economics graph?
An economics graph is a visual illustration of numerical data in economics.
Why are graphs very important?
Economics graphs simplify numerical data for easier readability and analysis without losing detail.
How do you interpret economics graphs?
To interpret a graph, we look at each point and trace its corresponding points on the vertical and horizontal axes. We then analyze the graph to interpret what it tells us based on economic theory.
What are some types of economic graphs?
The types of economics graphs are the line, bar and pie graphs.
What are the rules for plotting economic graph?
For line graphs, price or cost is on the vertical axis and quantity is on the horizontal axis. Pie graphs show categories as a fraction of a whole. Bar graphs can be plotted in numerous ways, generally with some type of numerical value on the vertical axis.
