I'm a newbie with GIS in general and QGIS specifically. I want to add an individual marker for each point on a layer. The marker is designed to convey data about the point in a visual manner. How do I do this? I have the markers in SVG and PNG formats.

1I think it's better to share an example dataset so the answer can be more relatable, it's easier for you to learn that way as well.– ConfusedButterflyOct 14, 2022 at 15:59

1I agree with @ConfusedButterfly, without more information you won't get a better answer than his answer (that is good but probably too generic for a beginner...)– J.ROct 14, 2022 at 16:41

How many points are there?– BERAOct 16, 2022 at 16:07

If you want each point to have a distinct marker, you need to add attributes for them. After each point has sufficient information, you can use Symbology -> Rule-based labeling according to an expression based on your needs.
Read https://docs.qgis.org/3.22/en/docs/user_manual/style_library/symbol_selector.html and Different SVG markers for different attributes for examples.

If it is just a question of rendering, and each marker should have a different symbol, going to categorize and use $id should be enough.– katagenaOct 15, 2022 at 9:24
