Final answer:
Icon sets display an image based on the value assigned to it, making it easier to interpret data at a glance.
Step-by-step explanation:
Icon sets display an image based on the value assigned to it. For example, in data visualization, an icon set can be used to represent different categories or ranges of data. Each icon within the set corresponds to a specific value or range, making it easier to interpret the data at a glance.
For instance, in a weather app, a set of icons may be used to convey different temperature ranges. A sun icon could represent a hot temperature range, while a snowflake icon could represent a cold temperature range. This allows users to quickly understand the weather conditions without having to read detailed numerical values.
