Is there a way to allow a user, after he has created a vector graph on a javascript svg canvas using a browser, to download this file to their local filesystem?

SVG

    Using FileSaver.js

    saveAs(new Blob([SVG_DATA_HERE], {type:"application/svg+xml"}), "name.svg")

    I made a clean/usable bookmarklet out of the suggestions.

    It will put a unique link next to every inline <svg> on the page.

    Hope it helps someone.

    It might be possible using the regular "Save" browser command, but it won't just save the SVG canvas, it will save the whole page.

    I believe your best bet is to use AJAX and send the whole SVG XML data as POST data to a server script, and have that script just send back the POST data with the header Content-Disposition: attachment; filename=yourfile.svg.

    (Under PHP, you can get the raw POST contents with file_get_contents('php://input').)

    $(document).ready(function(){	
     $("#btnDownload").click(function(){
    	var $container = $('#svg-container'),
         // Canvg requires trimmed content
        content = $container.html().trim(),
        canvas = document.getElementById('svg-canvas');
    	
    	// Draw svg on canvas
        canvg(canvas, content);
    	$container.hide();
        // Change img be SVG representation
        var theImage = canvas.toDataURL('image/jpeg');
    	
    	var a = document.createElement('a');
    	a.href = theImage; // xhr.response es un blob file
    	a.target = '_blank';
    	a.download = 'prueba'; // nombre del archivo.
    	a.style.display = 'none';
    	document.body.appendChild(a);
    	a.click();
    	delete a;
    });//fin function
    });// fin
