A Guide To Data Visualization – Part 1: Data Set


Data sets are the foundation of data visualization. If you have a bad data set, your visualization is going to be bad too. So how do you make sure that the data set is good? In this post I’ll go over the different types of data sets you need for your visualizations and how to make sure that each type fits your project needs perfectly.

A Data Set Is The Foundation Of Data Visualization

A data set is the foundation of data visualization. Data visualization is the process of creating graphics to communicate data. It can be used in many ways, including business intelligence, marketing and sales, education, public policy decision-making and more. A good example would be when you’re looking at a graph or chart online or in print that shows how much money each company has made from their products over time; this helps us understand what’s going on with their sales performance better than just reading numbers on paper would do alone!

Why Are Data Sets Important?

A data set is the foundation of any visualization. It’s what you use to create a graph or chart, and it contains all of the information necessary for you to understand your data.

If we look at an example from our last article (“Data Visualization: How To Tell A Good Story With Your Data”), we could say that there are two main parts: The first part is called “The Story,” which describes what happened in this particular case? And where did it happen? The second part would be “Who Was Involved?”

Let’s take a look at how these two questions relate back on how they were answered by our client (and therefore how they were answered by us). In order to answer these questions with confidence we had several sources available:

  • Interviews with key stakeholders who had been involved directly in developing this project; * Documents related specifically about this project such as presentations made at meetings etc…

Building The Big Picture

A data set is a collection of information, often stored in a database. It can be used to build your story, but it’s important to know how to use the right data set for telling the right story.

Here are some examples:

  • You want to tell an inspiring success story about how you helped a customer increase sales by 10{6f258d09c8f40db517fd593714b0f1e1849617172a4381e4955c3e4e87edc1af}. You could use this example: “We helped our customer increase their sales by 10{6f258d09c8f40db517fd593714b0f1e1849617172a4381e4955c3e4e87edc1af} within three months.” Or…
  • You want to show how much better your product or service is than your competitors’ products or services by showing how much better they perform on key metrics such as cost per lead or conversion rate over time. You could use this example: “Our solution costs $0.10 per lead compared with $1-$2 per lead from our competitors! This saves businesses millions every year.”

Data Set Types – Who Is Your Audience?

The type of data set you create depends on who your audience is. Here are some examples:

  • If you’re creating a report for senior management, you may want to use bar charts or pie charts. These types of graphs show the relationship between different groups in a way that makes it easy to understand at-a-glance. For example, if we were trying to show how many widgets each department sells per day and how much revenue they generate as a result (for simplicity’s sake), we would use a pie chart like this one:
  • If we wanted our audience to focus more on specific details about each department instead of just seeing an overall summary like above, then we might use line graphs instead – these lines are more detailed than those found in bar charts or pie charts because they can represent multiple variables at once. For example:

What Type Of Data Do You Have?

Now that you have an idea of what type of data to collect, it’s time to think about what type of data set is best for your audience. The first step in this process is determining exactly what information your audience needs from their visualization. For example, if you’re creating a dashboard for executives at a company who want to know how well their sales team is performing compared with their competitors, then there are several key pieces of information they will need:

  • Total revenue generated by each salesperson over time
  • Average revenue per sale by each salesperson

How To Change The Size And Shape Of Your Graphs For Different Audiences

When you’re creating a graph, it’s important to consider the audience. The best way to do this is by asking yourself what kind of information they will want and how they will use it.

For example, let’s say that we have two sets of data: one set has 10 items and another has 100 items. If we want our audience members (or ourselves) to compare these two sets, then we should probably use a bar chart or line graph instead of pie charts because those latter options don’t allow comparisons between multiple values.

Another example: if you have only one value in your dataset but still want an effective visualization for people who may not be familiar with statistics or graphs (e.g., children), then using scatter plots might be better than bar charts because they’re simpler yet still able to show patterns within large amounts of data

How To Display Text In A Graph Or Chart – Don’t Do This!

  • Don’t use more than one type of font
  • Don’t use more than one type of text
  • Don’t use more than one type of text size
  • Don’t use more than one type of text color
  • And finally, don’t put your labels in the wrong place!

How To Use Color Effectively In Data Visualization – Do This!

Color is one of the most powerful tools in data visualization, and can help you make your data stand out, highlight important information, show trends and patterns and differences between the different variables in your set.

Use color to make your data look more appealing

Color can also be used to make your visualizations more appealing by using contrast effectively. The visual appeal of a chart should not be underestimated; people are more likely to engage with an infographic if they like how it looks! It also makes sense from an aesthetic perspective – every person has their own preferences when it comes down to color palettes; therefore by creating visually appealing charts that match these preferences you will increase engagement levels even further (and hopefully keep them coming back).

A data set is the foundation of data visualization and you need to know how to create a good one.

A data set is the foundation of data visualization, and you need to know how to create a good one. Data sets are important because they help us understand the data. They’re the starting point for building your visualizations and understanding what you want your viewers or readers to take away from them.

Since there’s so much information out there now, it can be difficult for people who don’t know anything about data science or statistics–or even just Excel spreadsheets–to understand what they’re looking at in terms of numbers and graphs or pie charts (which we’ll talk about later). A lot of times when people see these things they think: “I don’t know what any of this means.” But if you have an interesting story behind those numbers then maybe something interesting will happen!


We hope this guide has given you a better understanding of what data sets are, how they work and why they’re so important. We know that it can be difficult to get started with data visualization but now that you know the basics we encourage you to try some new things! There are so many different types of graphs and charts out there – from pie charts to line graphs, bar charts or even maps – so why not find one that suits your needs?
