Understanding data visualisation

Data visualisation makes complicated data easier to understand by turning it into pictures like charts and graphs. This helpful tool makes it simpler to grasp what complex data is trying to tell us. In simple terms, it uncovers the hidden stories in complicated data and helps organisations see trends and patterns that might be hard to spot in the raw data.

Visual representation makes data easy to understand. For example, a line chart can show how sales change over time, helping companies see patterns like seasonal trends. Using visuals makes it simple to grasp important data, so we don't miss important insights among all the numbers.

Benefits of data visualisation for businesses

When data is easy to understand, companies gain several advantages. It helps them make better decisions based on solid information. Just by looking at a visual chart, decision-makers can quickly see the important points and take action to address any issues. For example, data analytics can use interactive dashboards to monitor real-time stock prices. This makes it easier for businesses to make timely and accurate investment choices.

Data visualisation improves communication within organisations. Instead of boring spreadsheets and reports, teams can use attractive charts and graphs to convey information. Graphics make it easy to get the point across quickly and effectively. For instance, data analysts can use data visualisation to monitor product results and share important information with their coworkers.

Types of data visualisation techniques

When it comes to data visualisation techniques, the options are many. Data analysts pick the right ones based on things like why they're showing the data, what kind of data it is, who's looking at it, and more. Here are some common ways to show data:


Charts are the easiest data visualisation technique to show the differences between data sets. There are different types of charts, including line, pie, and bar charts. While line and bar charts demonstrate the relationship between elements over time, pie charts show the proportions between elements of a whole.


This data visualisation technique facilitates distributing data sets over a 2D or 3D space. It shows how the data sets are related to the parameters on the plot. Scatter and bubble are the most commonly used plots. However, when it comes to big data, data analysts often use complex box plots to demonstrate the relationship between large volumes of data.


Maps are among the most popular data visualisation techniques used across various industries. They help locate elements in relevant areas or objects like building plans, geographical maps, etc. Heat maps, cartograms, and dot distribution maps are some of the popular map visualisations.

Diagrams and matrices

Diagrams mainly show the relationships or links between complex data sets. It includes various data types in one representation. Hierarchical, tree-like and multidimensional are the most commonly used visualisation types.

Matrix is an advanced data visualisation technique. It helps in establishing the relationship between different constantly updated data sets.
