What type of chart should I use?
However, numerical data alone is merely a combination of figures and doesn’t tell a story. The most meaningful data and/or data analysis in the world is useless if it’s not communicated correctly. Show
In her book Storytelling with Data, Cole Nussbaumer Knaflic writes:
Identifying the relationship between your data set or data points and telling the story behind the numbers will also encourage your audience to gain actionable insights from your presentation. How do you do this? You visualize data points through charts and different types of graphs. The good news is you don’t need to have a PhD in statistics to make different types of graphs and charts. This guide on the most common types of graphs and charts is for you. Keep reading if you’re a beginner with no data visualization background but want to help your audience get the most out of your numerical data points, both in-person and via a web conference. You’ll also discover data visualization best practices, advice from experts in the craft, and examples of well-thought-out charts and graphs below! Most Common Types of Charts and Graphs to Communicate Data Points With ImpactWhether you’re about to create a collection of business graphs or make a chart in your infographic, the most common types of charts and graphs below are good starting points for your data visualization needs.
1. Bar chartA bar chart, also known as a horizontal column chart, is popular for a reason — it’s easy on the eyes and quickly visualizes data sets. With bar charts, you can quickly identify which bar is the highest or the lowest, including the incremental differences between bars.

Best practices for bar charts
Pro-tip for bar charts from Jessica Witt of the Witt Perception Lab, a lab that focuses on information visualization and action-specific perception: “Bar charts must always have a zero baseline (y-axis value at zero) to ensure consistency.” Customize your bar graph with Piktochart’s bar graph maker.

For example, the line chart below highlights the increase in keyword searches for “remote work” across the US from February 1, 2020, to March 22, 2020. Interest in remote work surges as social distancing takes hold by IndeedWhen to use line charts

3. Area graphAn area graph is like a line chart as it also shows changes over time. One difference with these types of graphs is that area graphs can represent volume which is typically filled with color. The area graph example by the BBC below shows a simple comparison of two data sets over a period of time. Vaccine doses received in the UK up to May 30 2021 by the BBCWhen to use area graphs

4. Scatter plotA scatter plot or a scatter chart helps show the relationship between items based on two different variables and data sets. Dots (or plot data) are plotted in an x-y coordinate system. In some scatter plots, a trend line is added (like in the example below) to a scatter plot.

5. Pie chartPie charts highlight data and statistics in pie-slice format. A pie chart represents numbers in percentages, and the total sum of all pies should equal 100 percent. When considering charts and graphs to employ to visualize data, pie charts are most impactful to your audience if you have a small data set.

PictographDespite having ‘graph’ in the name, a pictograph doesn’t fall into types of graphs. Instead, a pictograph or a pictogram is a type of chart that uses pictures or icons to represent data. Each icon stands for a certain number of data sets, units or objects. For example, the infographic below contains a pictogram — each human icon represents 10 percent of CEOs.

7. Column chartA column chart is ideal for presenting chronological data. Also known as the vertical bar chart, this type of chart works if there are only a few dates to highlight your data set like in the example below. Column chartWhen to use column charts

8. Bubble chartA bubble chart or a bubble plot is a lot like a scatter plot. However, bubble charts have one or two more visual elements (dot size and color) than a scatter plot to represent a third or fourth numeric variable. Telehealth literature map by clinical focusWhen to use a bubble chart

Pro-tip from Elizabeth Ricks, a data visualization instructor on creating a bubble chart:
9. Gauge chartA gauge chart, also known as a dial chart, is an advanced type of chart that shows whether data values fit on a scale of acceptable (good) to not acceptable (bad). For example, you can create a gauge chart to display current sales figures and use your quarterly sales targets as thresholds. Not all charts are able to show data in this way. Gauge chartGauge charts are particularly helpful where the expected value of the data is already known. This helps organizations create actionable reports and help employees understand where they stand in terms of metrics by looking at the chart. When to use gauge charts

10. Stacked VennA stacked Venn chart is used to showcase overlapping relationships between multiple data sets. This type of graph is a variation of the original Venn diagram, where overlapping shapes or circles illustrate the logical relationships between two or more variables.

What About the Other Types of Graphs and Charts?There are plenty of other types of graphs and charts—line graphs, multiple line graphs, candlestick charts, Gantt charts, radar charts, stacked bar graphs, heat maps, waterfall charts, and the list goes on. They are almost always specific to a particular industry, and the charts and graphs we’ve listed should be enough to address your basic to intermediate data visualization needs to illustrate hierarchical data and beyond. Choose Charts and Graphs That Are Easiest for Your Audience to Read and UnderstandThoughtfully designed charts and graphs are a result of knowing your audience well. When you understand your audience, you can communicate your data points more effectively. Before you share your chart or graph, show it to a couple of colleagues or a small group of customers. Pay attention to their questions, their observations, and how they react to your chart or graph. If you’re looking for a graph maker, create a free Piktochart account and sharpen your data visualization chops by making the right types of graphs and charts in minutes from multiple data sets and beyond. Which type of chart is most appropriate?The column chart is probably the most used chart type. This chart is best used to compare different values when specific values are important, and it is expected that users will look up and compare individual values between each column.
