Data visualization types: the best-known visual representations of data & data visualization techniques

There are various types of data visualization, each with its own advantages and disadvantages. The most common and well-known visual representations of data are charts and graphs, which are excellent for conveying simple trends or relationships between variables.

However, they can be difficult to interpret if the analyzed data is complex or if there are many data points. In addition, charts and graphs can be misleading if they are not properly designed or used in conjunction with other types of data visualization.

Other common data visualization techniques include maps, timelines, and scatter plots. These techniques are often used to visualize more complex data sets and can be more effective than charts and graphs in certain situations.

Like all tools, data visualization should be used in a way that is appropriate for the specific task at hand. Choosing the right type of data visualization is an important part of effectively communicating information.

How does data visualization work?

Data visualization is the process that transforms raw data into an intelligible, coherent, and easy-to-understand pictorial format. It translates complex numerical information in a way that is easy to understand, interpret and put into storytelling.

Along with its capacity to reveal trends, patterns, and relationships in data, it can also be used to identify outliers and anomalies.

Data visualization techniques

There are countless ways to visualize data, but some techniques are more effective than others. When choosing a data visualization technique, it’s important to consider the type of data you’re working with and the message you want to communicate.

Some common data visualization techniques include:

➔   Bar charts: used to compare different categorical data points

➔   Line graphs: used for timeframes or to show how a numeric value has changed over time

➔   Pie charts: used to show how different parts make up a whole

➔   Scatter plots: used to show the relationship between two numeric values

➔   Maps: used to show data points on a geographical map

Other techniques are interactive maps, multisource dashboards, multilayer geo charts, geospatial context, or cross-filtering.

When working with large and complex data sets, it’s often helpful to use multiple data visualization techniques to get a better understanding of the data. For example, you could use a bar chart to compare the overall performance of different groups, but then use a scatter plot to drill down and see how individual values relate to each other.

 The best data visualization techniques are those that make the data easy to understand and communicate the desired message effectively.

Data visualization analysis techniques

There are several different data visualization analysis techniques that can be used to gain insights from data. Some of the most common techniques include:

➔   Data exploration involves looking at the data to get a better understanding of what it contains. This can be done using various techniques such as visual inspection, summary statistics and data mining

➔   Data cleaning is an important step in any data analysis process. It involves identifying and correcting errors in the data, as well as dealing with missing values

➔   Data transformation is an additional step in analyzing data, often necessary in order to make it more amenable to analysis. It involves converting the data into a format that is more suitable for the chosen analysis technique

➔    Statistical analysis is a broad category of techniques that can be used to summarize the data and/ or uncover relationships between variables. Common statistical analyses include regression, correlation, and cluster analysis

➔    Visualization is arguably the most important step in any data analysis process. Data visualization allows us to see patterns in the data that would not be apparent from looking at raw numbers alone

➔   Communication is the final step in the data analysis process. It involves conveying the results of the analysis to stakeholders in a clear and concise manner

Data visualization analysis techniques divide into two main categories:

Univariate Analysis Techniques for Data Visualization

There are several univariate analysis techniques that can be used for data visualization. The most common ones are histograms, bar charts, and line graphs.

Histograms are used to visualize the distribution of data. They show how often certain values occur in a dataset. Bar charts are used to compare different values. Line graphs are used to visualize trends over time.

Bivariate Analysis Techniques for Data Visualization

When it comes to data visualization, there are a variety of bivariate analysis techniques that can be used to create impactful and informative visualizations.

Some common techniques include scatter plots, line graphs, and bar charts. Scatter plots are a great way to visualize relationships between two variables.

They can be used to show how one variable changes in relation to another, or to identify clusters and trends in the data. Line graphs are another popular technique for visualizing relationships between variables.

They can be used to show trends over time or to compare multiple variables against each other. Bar charts are a versatile tool for visualizing data. They can be used to compare proportions, or to show changes over time.

No matter which technique you choose, the important thing is that your visualization is clear, accurate and easy to understand. With so many options available, it can be helpful to experiment with different techniques until you find the one that works best for you and your data set.

Benefits and disadvantages of data visualization

There are both benefits and disadvantages to using data visualization as a means of understanding data.

Good data visualization examples

There are many ways to visualize data, and the best visualization for a particular dataset depends on the nature of the data and the question you want to answer with your visualization. That said, there are some general principles that successful data visualizations follow:

➔    Good data visualization should be easy to understand. It should use simple shapes and colours that are easy to distinguish. The visualization should also use labels and annotations to make it clear what each element represents.

➔    Good data visualization should be visually pleasing. This doesn’t mean that it needs to be flashy or have fancy animations, but it should be well-designed and organized in a way that is easy on the eyes.

➔    Good data visualization should tell a story. The best visualizations will help the viewer understand not only the data itself but also the implications of the data. A good visualization will make complex concepts understandable and provide insights that would be difficult to glean from raw data alone.

With these principles in mind, let’s look at some specific examples of good data visualizations.

One great example of simple yet effective data visualization is this Index Mundi map of global internet usage.

This map uses colour intensity codes to show which countries have high internet usage (darker shades) and low internet usage (lighter shades). We can also see which countries have seen the biggest growth in internet usage over the past few years. This map is easy to understand and visually pleasing, making it a great example of good data visualization.

Another great example of data visualization is this line chart from NASA showing the global temperature trend from 1881 to the present day.

This chart clearly shows that the Earth’s average temperature has been rising steadily over the past years and makes it easy to see how unusual recent years have been in terms of global temperatures. This chart is again easy to understand and visually appealing. It tells a clear story about the data, making it an excellent example of good data visualization.
