Blueprint Editor Overview for Visual DataV Dashboard Design - DataV - Alibaba Cloud - DataV

Basic concept

Blueprint Editor is commonly referred to as Visual Programming or Flow-Based Programming. It defines interactions between layers through visual connections.

Benefits

Unlike node programming, Blueprint Editor ensures real-time and synchronization of interaction and data.
Blueprint Editor supports data request merging and data distribution.
Blueprint Editor can be modularized and split to focus on a single interaction link. You do not need to organize and standardize code. You only need to focus on business rules and interaction requirements.
Blueprint Editor supports original components and third-party components, making it developer-friendly.

Important
Third-party widgets developed by users must comply with the developer standards.
