I need a javascript library that can generate and visualize a one-root-one-leaf DAG. Something like in this image. one-root-one-leaf graph example

I've tried different famous libraries like cytoscape.js with dagre plugin, echarts with dagre plugin and others but didn't get a satisfying output.

I need a library that supports graphs with 4 main features:

• Directed graph has one root and one leaf.
• No edge crossings like in the image. All the edges are moving in one direction from the root to the leaf.
• I can specify the level of the node. For example, in the image, I need to specify whether node 2 will be in level 1 or 2.
• Supports drawing graphs horizontally.
