This topic describes some basic terms and concepts in the DataV documentation to help you better use the product.
a project
A dashboard created by using DataV based on data is a visualization application. DataV is a tool that converts data into various dynamic charts and maps to present data to users in real time. For more information about how to create a visualization application, see Use a template to create a visualization application on a PC.
Data Sources
When you use DataV to create a visualization application, you must first specify the data source where the raw data resides. DataV supports multiple types of data sources: databases, files, and APIs. For more information about how to add a data source, see Add a data source.
canvas
The canvas editor is the main visual function area of DataV. You can use a canvas to determine the layout and colors for a project, adjust the sizes and locations of charts, and preview the configuration of the project. For more information about how to use a canvas, see Canvas operations.
Blueprint template
Blueprint Editor is the main logical function area of DataV. You can use blueprints to configure logical connections and interactions between nodes and manage logs on the debugging preview page. For more information about how to use blueprints, see Configure Blueprint Editor.
