Sketsa SVG Editor is a vector drawing application based on SVG. It allows users to create vector graphics that can be scaled and printed at any resolution, without losing detail or clarity. It features various tools for optimizing content creation, and includes a property palette, a DOM editor, a source editor, a resource editor, SVG-specific shape tools, transformation tools, and additional illustration tools. It uses SVG as its native file format.
sMArTH is an equation editor built on open Web standards. The editor itself uses a SVG interface and the application logic is implemented in ECMAScript using the DOM. Both MathML and LaTeX are supported as exporting formats in addition to the SVG format. The most important mathematical content from both LaTeX and MathML is already provided, and this should cover the need of the majority of users. The graphical user interface allows even the most complex equations to be built with simple "Point and Click" techniques instead of writing convoluted typesetting code.
