Depending on what you be are diagramming you might want to use the C4 Model ( https://c4model.com/ https://c4model.com/) which often results in easier to understand diagrams. There is a PlantUML add on for it too: https://github.com/RicardoNiepel/C4-PlantUML https://github.com/RicardoNiepel/C4-PlantUML Also draw.io templates and a set of Visio templates ( https://github.com/pihalve/c4model-visio-stencil https://github.com/pihalve/c4model-visio-stencil ) that can be imported into Lucidcharts as well. There is also some web based tools (see bottom of C4 website).
