Feynman Diagram Editor
A web take on JaxoDraw: pick a propagator,
click-and-drag to draw, then drag the midpoint handle to bend a line into an arc. Everything
stays in your browser, and the diagram exports as
axodraw2 LaTeX, SVG or PNG.
axodraw2 LaTeX
Drawing tips: after drawing, the tool switches to Select — drag the blue
endpoint handles to reconnect lines (they snap to nearby vertices and endpoints), drag the
hollow midpoint handle sideways to bend a propagator into an arc, and drag a loop's hollow
handle to resize it. The Loop tool draws a closed circle using the last
propagator type you picked; the dropdown changes the type of whatever is selected.
Double-click a label to edit it — labels are typeset as real math (MathJax), so
$e^-$ or $\frac{1}{2}$ render identically on
the canvas and in the SVG/PNG downloads, and export verbatim into \Text.
Arrow keys nudge the selection (Shift for bigger steps), Cmd/Ctrl+D duplicates.
