# Build Dashboards and Visualizations in Data Hub

> Create trend and comparison visualizations in Data Hub, and pin them to a metered entity's default dashboard for digital signage or web embedding.

A Data Hub dashboard is a saved collection of visualizations for a metered entity — see [Core Concepts](/core-concepts#visualizations) for how visualizations, dashboards, and metered entities relate.

## Visualization types

Data Hub visualizations fall into two categories:

**Trend Analysis** — tracks one or more variables over time:

* Single Point Line / Bar Trend Analysis (one variable)
* Multi Point Line / Bar Trend Analysis (multiple variables)
* Heatmap Analysis (data intensity across time or other dimensions)

**Comparison** — compares variables or entities side by side:

* Bar Chart Comparison
* Portfolio Comparison (proportional, hierarchical view)

Visualizations can be filtered by geographic region, organization, building type, specific metered entity, and resource type, and can reference Typical Usage or a Previous Period for context.

## Setup vs. View

Every visualization has two distinct surfaces:

* **Setup** — where the visualization is configured (which variables, time window, chart type, filters).
* **View** — the actual public-facing URL of the rendered visualization, used for digital signage displays and web embeds.

Customization options differ between the two — some display options (like show/hide header or chart title) are set via URL parameters on the View link rather than in Setup.

<Note>
  This page is a stub for the exact Setup workflow (where in the navigation to create a new visualization, how to select variables and a chart type step by step). That click-by-click walkthrough hasn't been written up yet — see [Sharing & Exporting](/guides/sharing-exporting) for how a finished visualization's View link is used for embedding or digital signage.

## Pinning to a default dashboard

Each metered entity has a **Default Dashboard** and a set of **Default Variables** (the variables representing total usage per resource) that appear there. See [Core Concepts](/core-concepts#metered-entities) for the full metered-entity metadata model.
