# Data Lineage Dashboard

The Data Lineage Dashboard helps visualize the complete data journey from source to destination. It provides a unified and interactive interface that enables users to explore data lineage at multiple levels.

**Key Features**

* **Single View (Hybrid of Flow and Sankey):**\
  The current version introduces a simplified, single view combining both Flow and Sankey views into one cohesive interface.<br>

* **Connection-to-Connection Lineage:**\
  The default view now focuses on connection-to-connection lineage. Each connection is represented as a block, and lines between blocks indicate the lineage relationships.<br>

* **Enhanced Navigation:**\
  Users can now navigate to the column level by clicking on the lines connecting the blocks, allowing for a more granular exploration of the data lineage.<br>

The Reset button in the Lineage graph repositions all nodes to their original structured layout. It provides a quick way to clear any manual adjustments and restore a clean, organized view of the data flow. This function is especially useful when navigating large or complex lineage diagrams.

**Functions of the Reset button include:**

* Repositions all nodes to the default structured layout
* Clears manual changes to node positions
* Improves clarity and alignment in complex data flow graphs
* Saves time by avoiding manual rearrangement
* Maintains a consistent visual structure for easier analysis

## Visual Representation

* **Nodes and Links:**\
  Connected data objects are represented as nodes, while the data flowing between them is defined as links.
* **Schema Representation:**\
  Schemas or data sources are visually depicted as boxes or nodes, indicating where data originates or is stored.
* **Arrows or Lines:**\
  Arrows or lines connect schema nodes to indicate the direction of data flow. This provides a clear and simplified view of how data moves across different schemas.

This schematic layout enables users to understand the overall flow of data between schemas quickly.

### Granular Exploration with Sankey Diagram

The Dashboard provides a detailed, hierarchical view of data lineage through a Sankey diagram—a network-like structure that visualizes complex data movements and transformations across schemas, tables, and columns.

**Components and Interactions**

* **Nodes:**\
  Represent connected data objects, such as schemas, tables, and columns.
* **Links:**\
  Visually represent the data flow between nodes. The width of a link corresponds to the volume of data transferred.

### Levels of Lineage Visualization

* **Schema-to-Schema Flow:**\
  Visualizes the movement of data between entire schemas.

* **Table-to-Table Flow:**\
  Clicking a schema node drills down to the table level, displaying the tables involved in lineage between the selected schemas.

* **Column-to-Column Flow:**\
  Clicking a table connection further drills down to column-level movement, showing how specific columns map and transform data between schemas.

* **Data Mapping and Transformations:**\
  The Sankey view highlights how data is processed and transformed throughout its journey, helping users identify potential data quality issues.
