This topic describes the basic terms used in the DataV documentation. Understanding these terms will help you use this product more effectively.
Visualization application
A visualization application is a dashboard that you create in DataV to visualize your data. It transforms raw data into dynamic charts to present information in real time. To quickly create a visualization application, see Create a visualization application for PC from a template.
Data source
To create a visualization application in DataV, you must first specify a data source for your raw data. DataV supports multiple types of data sources, such as databases, files, and APIs. For more information about how to add a data source, see Add a data source.
Canvas
The canvas, also known as the canvas editor, is the main visual design area in DataV. You can use the canvas to manage the page layout and color scheme, arrange the size and position of charts, and preview the visualization application. For more information about how to use the canvas, see Canvas operations.
Blueprint
The blueprint, also known as the blueprint editor, is the main logic configuration area in DataV. You can use the blueprint editor to connect nodes, configure interactions, and manage logs on the debug preview page. For more information about how to use the blueprint editor, see Configure the blueprint editor.
Toolbar
The toolbar is located above the canvas. It contains controls to return to the console, show or hide bars and panels, set project filters, view widget updates, configure tools, switch the canvas for mobile migration, configure the blueprint editor, configure widget deletion and backup, publish, preview, get help, and report errors.
Component
In the canvas editor, you can select a widget from the expanded All Assets list to add it to the canvas.
