Possible disadvantages of The Data Visualisation Catalogue

• Limited Interaction Features
  While informative, the website lacks interactive features such as hands-on tutorials or interactive chart builders that could enhance learning and application.
• No Customization Guidance
  The catalogue provides general advice on using various charts, but it doesn't offer much detail on how to customize visualizations for specific datasets or software tools.
• Dependency on External Tools
  Users need to rely on external software tools to create the visualizations, as the website itself does not include built-in tools for generating charts.
• Occasional Overwhelm
  The extensive range and detailed information might overwhelm some users, particularly those new to data visualization, making it difficult to choose the right chart type.
• Design Overlook
  The website focuses more on explaining chart types and their uses rather than offering insights on aesthetic design and user engagement, which are also crucial in data visualization.
• Outdated Content Risk
  There is a risk that some information might become outdated as new visualization techniques and tools emerge, although it is periodically updated.
