Exclude

Definition

To exclude means to intentionally leave out or not include certain data points or elements from a dataset or visualization. This process is crucial in data visualization as it allows for the simplification of information, ensuring that only relevant data is presented to the audience. Excluding data can help to reduce clutter, enhance clarity, and improve the overall focus of a visualization, making it easier for viewers to grasp key insights without distractions.
