Hi!

The only way I found is an asynchronous call to a Java script function for chart component:

    chart.getElement().executeJs("""
                var svgBlob = new Blob(
                    [$0._root.renderToSVGString({})],
                    {type:"image/svg+xml;charset=utf-8"}
                );
                var svgUrl = URL.createObjectURL(svgBlob);
                var downloadLink = document.createElement("a");
                
                downloadLink.href = svgUrl;
                downloadLink.download = "newesttree.svg";
                document.body.appendChild(downloadLink);
                downloadLink.click();
                document.body.removeChild(downloadLink);
            """);

This snippet uses the renderToSVGString() method.
There is documentation for this method: Documentation - Apache ECharts

The only problem is that setting the choice of rendering method is not yet available.
I created an issue to implement the ability to select SVG as a renderer:

Unfortunately, there is currently no way to programmatically initiate a chart export.
