How to show points on LineString in QGIS?

Question

I created a shape file with the following schema in python:

    schema = {
        "geometry": "LineString",
        "properties": {"id": "int"},
    }

When I import this shape file to QGIS I don't see where the vertices/points of this polyline are, is there a way to show them?

Answer 1

Add a new symbol layer of type marker line and opt to show a marker on every vertex. Eventually click on the said marker to customize it.

Answer 2

Add a new symbol layer () of type Geometry Generator and select the geometry type to Point / Multi Point use this expression: nodes_to_points($geometry).
