Markersfunction

Markersfunction is a generic term used in data visualization and mapping to describe a utility or function that generates and positions markers for data points on a chart, map, or diagram. It is not a standard built-in in any single library, but several libraries expose similar capabilities under names like createMarkers or generateMarkers. The concept focuses on turning datasets into marker descriptors that visualization routines can render.

Usage and signature. In common practice, markersfunction takes a collection of data points and a set of options, returning an array of marker objects. Typical inputs include an array of coordinates or objects with latitude and longitude or x/y values, and options such as marker type, size, color, shape, label, and z-order. A minimal signature is markersfunction(data, options). The returned markers include properties like id, position (x, y or lat, lon), style, and optional metadata such as value or category.

Behavior and features. Markersfunction may support filtering, clustering, or sampling to limit the number of markers shown for large datasets. It can apply coordinate transforms, handle responsive sizing, and integrate with event handlers for interactivity. Some implementations support animated appearance or dynamic updates when the underlying data changes.
