# Shapes and lines

> What each shape, outline and line on the map means.

The map is 3D by default and turns slowly; switch to 2D with **3D | 2D** at the bottom left. The **legend** button next to it explains everything below.

![The map's legend: node shapes, outlines, edge styles and moving dots](https://mintcdn.com/xerg/Xfd-lD2nNpiXaLb6/images/legend.webp?fit=max\&auto=format\&n=Xfd-lD2nNpiXaLb6\&q=85\&s=b6e1d2667f5aeab5f26190179b5eaeb4)

## Shapes

| Shape | What it is |
| - | - |
| An area with a name on top | A repo, round its apps |
| Circle | An app inside a repo |
| A service's logo (or a diamond) | An outside service. Bigger when two or more apps use it |
| Small tile | A service only one thing uses. Its name shows when you point at it or zoom in |
| **+N** chip beside a service | That service's cloud resources (two or more), folded together. Lines to them go to the service. Click the chip to show them |
| **+N** chip elsewhere | More services only that item uses, on maps of over 150 items. Click to show them |
| Triangle | A cloud resource, like a Worker, bucket, database or queue, once its chip is open |

## Outlines

| Outline | Meaning |
| - | - |
| Hairline | Connected: seen live in a [connected account](https://xerg.ai/docs/connect/overview.md) |
| Dashed | Found in code, not connected yet |
| Dotted and faded | Unrecognized: looks like a service from an env variable name (say `LOB_API_KEY`), but isn't one Xerg [knows](https://xerg.ai/docs/map/recognized-services.md) |
| Green | Matches the highlight or your search |

With [setup's](https://xerg.ai/docs/setup.md) **Find services the code no longer uses** on, a service no source file imports or calls is drawn faded, whatever its outline, and its details say **Unused**.

## Lines

* **Solid**: confirmed. A repo contains it, or a connected account shows it live.
* **Dashed**: found in code. A package, env variable or config file points to it.
* **Arrows** point from what uses to what's used.
* A repo's own line (something it uses that none of its apps does) starts from a dot in its area.

Moving dots show traffic on the selected item's lines. See [Traffic and webhooks](https://xerg.ai/docs/map/traffic-and-webhooks.md).

## Getting around

* **Point** at an item and it grows, like the macOS Dock, and the turn holds.
* **Click** an item's icon or name for its details: what it is, where it was found, what it connects to.
* **Drag** an item to nudge it.
* **Isolate** (or press **I**) shows only the selected item and what it's linked to. **Esc** brings everything back.
* **Search** and highlights are in the panel at the top of the map (open it with **+**). Selecting a folded resource from search or the inventory opens its chip.
* **Inventory** shows every item as a table, cloud resources by their own type (Worker, D1 database, S3 bucket). It opens on the first row's details; **not connected** opens that item's details too.
