Note: this repository was recently moved from PowerBI-Visuals. This repository contains information about the core PowerBI Visuals and reference for custom visuals developed using the old method / tools.

If you are creating a new custom visual it is highly recommended that you use the new api / tools learn more

Microsoft Power BI visuals Core [DEPRECATED]

This repository is deprecated. Please use PowerBI-visuals instead.

The Microsoft Power BI visuals project provides high quality data visualizations that you can use to extend Power BI. The project contains over 20 visualization types, the framework to run them, and the testing infrastructure that enables you to build high quality visualizations. The framework provides all the interfaces you need to integrate fully with Power BI's selection, filtering, and other UI experiences. The code is written in TypeScript so it's easier to build and debug. Everything compiles down to JavaScript and runs in modern web browsers. The visuals are built using D3 but you can use your favorite technology like WebGL, Canvas, or SVG. This gives you everything you need to build custom visualizations for Power BI.

What is included

Source code of all the visuals used in Power BI.
A Playground app to help you try out the existing visuals, and experiment with the ones you have created.

Getting Started

Prerequisites

To build the library and run the sample application you will need:

Git
Node.js (>= 4.x <= 5.x)
Recommended IDE - Visual Studio Community 2015 (Free for use)
- Be sure to install the "Microsoft Web Developer Tools" optional feature. To install, go to Add/Remove Programs, right-click on Visual Studio, select Change, then Modify. Check the "Microsoft Web Developer Tools" checkbox and finish the install.
- Ensure that Visual Studio is not using previous version of Node.js. Go to Tools > Options, then Projects and Solutions > External Web Tools. You can remove old path and add folder with the latest Node.js, or just leave $(PATH) and move it above all folders, if PATH environment variable contains path of the latest Node.js.
- You can install VSIX Package and use Visual Studio Template from it to create new Visual.

One-Time Setup

In order to build the Power BI visuals, ensure that you have Git and Node.js installed.
