Most Popular Data Visualization Techniques and Tools

Estimated reading time: 10 minutes
Nowadays, we are immersed in a wealth of information. It becomes more difficult to present content in a way that highlights you in the flow of data and helps to be remembered.

80–90% of this information is visual. Data visualization helps quickly convey any thoughts and ideas, sets emphasis, and draws the consumers' attention to the main points of the content. And most importantly, it meets the needs of the audience and attracts more traffic to the site.

Today, there are plenty of special methods and tools for data visualization: some are quite simple, while others are more difficult and may require customization or some skills.

In this article, we'll talk about the best data visualization solutions and best practices. How to do it right? Which techniques/tools can you apply? What is the difference? How to pick the one that will definitely work for you? We have selected various proven options: both for those who need a quick and understandable result and for advanced users who want something more sophisticated.

Best Data Visualization Techniques

Ok, data visualization is a must-have for any presentation of information. For each kind of data, you must select a certain visualization method to convey info more clearly and correctly.

There are countless ways to visualize data, we will touch only some of the most common ones. You can find charts, plots, maps, diagrams, matrices, tables among the popular data visualization techniques. You can pick any of them and tune their characteristics. Below we will review them, and analyze instances of implementation and cases as well as benefits and limitations.

Charts

This is the most common method to showcase the progress of one or some data kits. It is a descriptive visualization mode in which bars, lines, and slices represent the content. The issue is that if the technique is chosen incorrectly, a consumer may misinterpret the data.
Line Charts
A line chart displays the dynamics for one or more indicators. It is convenient to apply for comparing changes of various datasets over time. It may be statistics on viewing landings, the progress of the cryptocurrency rate, or any seasonal fluctuations. The main benefit is simplicity.
Bar Charts
A bar chart is one more technique that is perfect for comparing multiple datasets. Horizontal charts are selected when required to collate many indicators or underline the superiority of one of them. And the vertical ones perfectly illustrate how the indicators have varied in different periods. For instance, it can be an analysis of the enterprise's annual income over 10 years.
Pie Charts
A pie chart displays the constituent units between the pieces of a whole. The aim is to portray the composition of a dataset — what it consists of. For instance, the percent of total sales that each goods' category brings. The issue is that they are not always easy to interpret, especially when there is too much data to compare.
Gauge Charts
A gauge chart is very similar to a pie chart, with an arrow to represent data points. Also known as a speedometer chart or a dial chart, it is one of the most common visual tools to introduce progressive values. The gauge chart isn't restricted to displaying just one parameter. It shows the maximum, the minimum, and the current value of the analyzed data. The dial usually consists of several colors that share the scale into parts and allows us to understand the information clearly.
Historigrams
A histogram is a type of graphical representation, a kind of bar chart that is used to display statistical info in columns to show the frequency distribution of continuous data. It organizes information in a specified range and points to the data that lies between these ranges of the values. Histograms are primarily used in statistics to showcase certain types of variables in the given information.

Plots

These techniques divide two or more datasets in two-dimensional or even three-dimensional space to portray the connection between these kits and the metrics on a graph. The most widespread are bubble and scatter visualization methods.
Scatter plots
A scatter plot helps detect and visualize the connection between two continuous variables. It is applied to define the level of effect of two numeric variables on each other.
Bubble plots
A bubble plot helps match two parameters by the third. As a rule, bubble plots are used to match and denote relationships between different bubbles by their position and size. A bubble plot is ideal if you have three or more variables in your data.

Maps

Maps are another popular technique among the best tools for data visualization, which allows placing elements on the pertinent objects and zones.
Heat maps
Heat maps visualize data in colors, enable comprehensive analysis of multidimensional data by distributing variables in rows and columns, and coloring table cells. They are valuable for mapping the changeability of variables, identifying the patterns, presenting the analogous characteristics of variables, and determining the connections between them.
Geographic maps
Geographic maps are great when needed to see the spreading of any indicator by region, country, or mainland.
Dot distribution maps
Dot distribution map is a technique that applies a "dot" symbol to show the presence of an object or phenomenon. This map is best used for browsing data, but it is not very convenient for working with specific data.
Cartograms
Cartograms show divisions by geographic areas or regions, highlighted in colors.

Diagrams and matrices

Diagrams
Diagrams are typically applied to depict complicated connections and unit diverse types of data in one whole visualization. They're usually used for structuring and process visualization in different use cases such as strategic plans, service portfolios, organizational structures, software architecture, etc.
Matrices
Matrices are one of the main data visualization methods that can define the interconnection between several permanently updating datasets. They usually show data in a grid format and are used to display crosstables that can be hard to read otherwise.

Tables

A table is an effective method of presenting data when precise values are crucial since numbers better illustrate general trends.

Unlike charts, which use abstraction to identify trends and numerical relationships, tables show data as close to its initial form as possible. Tables are intended to be read, so they are the best solution when you have data that you cannot easily visualize or when the information needs more attention. Accuracy is essential in spreadsheets, allowing you to go deeper into numbers and learn the exact values instead of concentrating on approximation or visualization.

However, tables can also be simple and complex. Filtration and sorting can be applied to them. They can be used with expansion and collapse functions, and show greater details and specifics, providing users with a complete picture. Sometimes tables may include charts within them for more accuracy.

The Most Popular Data Visualization Tools

Next, we'll talk about the best tools to generate stunning representations and interactive data visualizations. Some are lighter, while others are more difficult; some offer the broadest functionality, while others have relatively limited opportunities; some are intuitive, while others are difficult to learn.
