5 Top Tips for Effective Data Visualisation



Top Tip 1 – Define the purpose and audience

Before creating a visualisation, it’s important to define the purpose and audience of the visualisation. What message do you want to convey, and who will be viewing the visualisation? This will help you choose the appropriate chart type and design elements.


Top Tip 2 – Choose the most appropriate chart type

There are many different chart types to choose from, each with its own strengths and weaknesses. Some common chart types include:

  • Bar charts: Used to compare values across categories
  • Line charts: Used to show trends over time
  • Scatter plots: Used to show the relationship between two variables
  • Heat maps: Used to show the distribution of values across categories
  • Treemaps: Used to show hierarchical data


Top Tip 3 – Keep the design clear and easy to understand

Once you’ve chosen the appropriate chart type, it’s important to design the visualization in a way that is clear and easy to understand. Some tips for designing effective visualizations include:

  • Limit the number of variables: Too many variables can make the visualisation cluttered and confusing.
  • Use color strategically: Color can be used to highlight important information, but too much color can be overwhelming.
  • Include clear labels and titles: Labels and titles should be descriptive and easy to read.
  • Consider the layout: The layout should be intuitive and guide the viewer’s eye to the most important information.


Top Tip 4 – Use interactive features

Many visualisation tools, such as Tableau and Power BI, offer interactive features that allow viewers to explore the data in more detail. This can help viewers gain a deeper understanding of the data and make more informed decisions.


Top Tip 5 – Test and refine the visualisation

Once you’ve created the visualisation, it’s important to test it with the intended audience and gather feedback. This feedback can be used to refine the visualisation and make it more effective.
