 The brush transform is similar to the [pointer](./pointer.md) transform: it interactively filters the mark’s index to show a subset of the data, and re-renders the mark as the selection changes. Since the mark is lazily rendered during interaction, it is fast: only the visible elements are rendered as needed. And, like the filter and select transforms, unfiltered channel values are incorporated into default scale domains.
 
-The brush transform supports both one- and two-dimensional brushing modes. The two-dimensional mode, [brush](#brush-options-1), is used above and is suitable for scatterplots and the general case: it allows the user to define a rectangular region by clicking on a corner (_e.g._ the top-left corner) and dragging the pointer to the bottom-right corner. The one-dimensional modes, [brushX](#brushx-options) and [brushY](#brushy-options), in contrast only consider one dimension; this is desirable when a chart has a “dominant” dimension, such as time in a time-series chart, the binned quantitative dimension in a histogram, or the categorical dimension of a bar chart.

 The brush transform emits an [*input* event](https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/input_event) whenever the selection changes, and sets the value of the plot element to the selected data. This allows you to use a plot as an [Observable view](https://observablehq.com/@observablehq/views) (viewof), or to register an *input* event listener to react to brushing.
