We present work-in-progress on the design and implementation of a Web framework for building Immersive Analytics (IA) solutions in Virtual Reality (VR). We outline the design of our prototype framework, VRIA, which facilitates the development of VR spaces for IA solutions, which can be accessed via a Web browser. VRIA is built on emerging open-standards Web technologies such as WebVR, A-Frame and React, and supports a variety of interaction devices (e.g., smartphones, head-mounted displays etc.). We elaborate on our motivation for focusing on open-standards Web technologies and provide an overview of our framework. We also present two early visualization components. Finally, we outline further extensions and investigations.
