For purposes of color-coding on this map, companies are divided into broad sets of Department of Labor (DOL) industry groups as shown in the set of colored pointers and corresponding labels under the map. To limit the companies to those in one or more industry groups, click/tap a colored pointer or its label (like "Manufacturing"); to restore the original view of all companies, click/tap "DOL Industry Group" to the left of the pointers and labels. Alternatively, once you have selected one or more groups, you may click/tap the tag that appears for a group to remove it from your view.
You can explore the map by zooming in and out or by using the search box at the upper right of the map. (Selecting a search result will limit the map to that company. To restore the original screen, you can, for example, click/tap the tag for your search results that appear near the bottom of the map area, or click/tap the small circular arrow in the upper left of the map.)
To group the map by other parameters, hover over or click/tap "DOL Industry Group" in the lower-left portion of the map and select a grouping from the menu that pops up.
