I am always fascinated by the kind of diagrams that people publish in Cell, Nature, Science etc.. I want to get such a software that can help me in my research.
Popular, free and user-friendly tool is Tableau Public. Other are described for example in ComputerWorls article: 22 free tools for data visualization and analysis.
@Ajay, I assume you mean free software when you say open access. You can find several pieces of software for your purpose and similar ones here on Juan-Esteban's post linked below.
For complex data visualization, you can try the programming language R.(there is a free tutorial on R at CodeSchool).
If you just need an easy to use drawing program for mainly vectorized graphs (fine for display and print) of all kind, I suggest Inkscape to Ahmad's list above.
I would strongly recommend the R programming language. Particularly, the ggplot2 package offers great possibilities and flexibility to make and export all type of plots.
Adobe inDesign is also a very good and intuitive tool to create scientific illustrations.
Dear Ajay Kumar . See the following useful link: https://www.ilovephd.com/10-simple-online-drawing-tools-for-effective-thesis-diagrams/#:~:text=Inkscape%20is%20professional%20quality%20vector,Graphics)%20as%20its%20native%20format.
Mahipal Shekhawat agrees with the Biorender tool. But it is free for five diagrams only. Is there any other way (without having any subscription) to make an unlimited diagram?
normally people use even power point. You can design various sophisticated diagrams, but you might need to have some graphic design skills but i do believe there are some softwares. i have seen or used power point and also INKscape (should be free) and GIMP sometimes to perform some photoshopping
Hi, some of them are made by ggplot package. You can use python or R to create them, there are a lot of tutorials on youtube (and others) to do them w/o programing skills. Also try this online tool https://shiny.gmw.rug.nl/ggplotgui/ .
pd: you have more packeges besides ggplot, check them!
I have tried some and ended up using Veusz. It is really versatile, cross-platform and full of features. Perhaps, you should give it a try. It is already in the repositories of modern Linux distros, Ubuntu, for instance. Otherwise, see https://veusz.github.io .
