What type of data does a histogram visualize in Tableau?

A histogram visualizes numerical data grouped into bins, which are intervals that segment the data range. This allows for the assessment of the distribution, frequency, and spread of the numerical data in a visual format, making it easier to identify patterns, trends, and outliers.

In Tableau, when creating a histogram, users specify a measure (a numerical field), and the software automatically organizes the data into these bins based on the selected range and size. This binning process facilitates the visualization of how data points are distributed across various ranges, revealing the density of occurrences within each bin.

The other options reflect different types of data visualization approaches in Tableau. Categorical data is typically visualized using bar charts or pie charts, whereas text data may be presented in word clouds or tables. High-level summaries of data can be shown through dashboards or summary statistics but do not specifically relate to the binning and distribution methods used in histograms. Thus, the focus on numerical data in bins distinctly characterizes the primary function of a histogram.
