What is data visualisation?

Welcome to the Nightingale HQ overview of data visualisation services. Here we aim to introduce people to what they need to know.

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.

Business function leader view

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.

You may need this service if:

  • your team needs a clear, at-a-glance overview of performance on a regular basis.
  • your team regularly reports on performance to executives or clients.
  • your team is missing opportunities to act on data insights due to lack of time or analysis skills.
  • you want to gain insight into customer behaviour, market segmentation and marketing campaign performance.

KPIs you should consider measuring for this are:

  • improved conversion rate at all levels of your funnel
  • reduced stock waste
  • improved retention rates
  • reduced overspend

Technical view

Data visualisation makes your company’s data more accessible to those who can act on the insights to improve performance. Implementing data visualisation may require you to perform a data audit to get an overview of your data’s sources, storage locations and relationships (seedata modeling). Introducing data visualisation tools in your organisation will reduce the load on IT teams as access to data insights can be passed on to team leaders.

Data visualisation helps deliver:

  • actionable insights and feedback
  • improved accessibility of data insights
