Often we service in locations where the software is incomplete, it's wrong I got a presentation to create a network diagram at the branch office, Microsoft Visio is not available because of the problem, and this made me an alternative choice like him. But because of the limited read speed it is sometimes better to use an online solution to create diagrams.
Impact there is still hope from Google search results. One of the diagramming services online is Cacoo which is also available free version, in this emergency accident I found on the internet and now has a free account.
You can create different types of diagrams here, from Flowchart, UML, Mindmap, ER Diagram, and more. Therefore I submit the diagram online versatile, for most needs are complete types. And here I need to create a network diagram for visualizing the network structure in the office.
How to use Cacoo itself is easy, just select the type of diagram you want to make and click on the desired element then place on the canvas provided. You can manage relationships between elements, add text or text to each object, resize it and more. I am even overwhelmed because of the many options in the design, just need a simple diagramming.
When finished you can diagram in your account, also can be PNG image, PowerPoint presentation, PDF, SVG vector image, and PostScript. So you can immediately make the diagram results.
