What is data visualisation?

Definition of data visualisation

From Wikipedia

Data visualization is the graphic representation of data. It involves producing images that communicate relationships among the represented data to viewers of the images. This communication is achieved through the use of a systematic mapping between graphic marks and data values in the creation of the visualization. This mapping establishes how data values will be represented visually, determining how and to what extent a property of a graphic mark, such as size or color, will change to reflect change in the value of a datum.

Executive view

Data visualisation empowers all of the teams in your organisation to make data-driven decisions and act on insights from your data. By displaying data as visual charts such as bar charts, line charts and maps, gaining insight is a quicker and more accessible process. This saves time and resources in communicating and understanding data.

Data visualisation helps businesses:

• to make data-driven decisions.

• to reduce the cost and time required to gain insight from data.

• to make actionable data insights available across the organisation to improve KPIs.

Data visualisation makes data insights accessible to everyone and empowers your teams to take data-driven actions efficiently. You might build a shared data dashboard for your team so that everybody can gain a clear overview of your team’s performance quickly, and act on the insight. You may also build reports and dashboards to share with executive teams and clients to demonstrate the value of your team’s work and highlight KPIs.

Data visualisation makes your company’s data more accessible to those who can act on the insights to improve performance.
