Khartis is young and propose, for now, 4 types of classic visualization: proportionnal symbols and colour ranges to show quantities, and variations of shapes/colours/size to distinguish categories, both on coordinates (points) or territories (areas). This combination of visualiztions offers, right now, a wide range of results. We are working on other visualizations... Be carreful!
Yes, Khartis allows you to save all your map settings, data included. Then, you can import this project file to resume your work.
You can export your map as SVG (vector format) or as PNG (raster, with pixels). Both can be immediately opened into a browser or inserted into a report, a slideshow, a 3D printer a plane or any publication, printed or online. A raster editor such as Gimp or Adobe Photoshop allow to modify a PNG file. A vector editor such as Gravit (free and online) or Adobe Illustrator enable to modify SVG file.
