What is the simplest way to display images representing dimension groupings?

The simplest way to display images representing dimension groupings is to create a URL as an ungrouped dimension. This method allows you to link images from an external source or a centralized storage location, making it easy to associate specific images with each dimension grouping. By using URLs, you can dynamically reference images without worrying about the limitations of device storage or the technical complexity of embedding them within visualizations.

Using URLs also simplifies updates; if you need to change an image, you can simply update the link rather than re-uploading or re-embedding images across multiple instances. This approach offers efficiency and flexibility, particularly when managing large datasets or when images are subject to frequent changes.

In contrast, storing images on the device can lead to issues with accessibility and capacity, especially when working across different platforms. Embedding images in a data narrative might complicate the presentation by increasing file size or making visuals less interactive. Uploading images directly in chart properties, while sometimes effective, can create redundancy and additional management overhead, particularly if images need to be modified later. Thus, using a URL as an ungrouped dimension emerges as the most streamlined and effective option for representing dimension groupings with images.
