Creating and adding new elements with js in svg is successful, but cannot be displayed (SVG development practices)
First, change node = svgdoc. createElementNS ('www .w3.org/2000/svg', 'rect ') at 1. It is required to create a svgRect element.
Second, IE8 does not support svg. When running this file in IE9 or later, dynamic content will be blocked. A prompt will be displayed at the bottom of the page. Click allow. Firefox and chrome can directly run this file.

SVG cannot display Chinese Characters
Young people. The function you use is File SVGOutputFile.
I think your SVG images are dynamically generated. Let me give you an example.
Let's take a look at your example.

Import java. lang. Math;
Import java. io. File;
Import java. io. FileWriter;
Import java. util. ArrayList;
Import java. util. List;
Import java. util. Random;
Public class generateontology {

Public static void main (String [] args ){
List list = new ArrayList ();
List. add ("Mathematics ");
List. add ("Chinese ");
List. add (" ");
String path = "F :\\";
RenderSVGGradientOnToLogy ("abc", list, path );

}
Public static void renderSVGGradientOnToLogy (String username, List list, String path ){

// Here is the hard-coded coordinate of the center, which can be modified,
Int CirCenterX = 500;
Int CirCenterY = 400;
Int r = 50; // radius of the circle
Int length = 100; // The length of the ray.
Int LineEndX = 0;
Int LineEndY = 0;
Int CirSecEndX = 0;
Int CirSecEndY = 0;
String NewDirectPage = "SVGSecInstance. jsp ";

Int ListAcount = list. size ();

// This is where we find out what the largest value contained in each of the array is,
// Its a simple loop that goes through each value passed, and determines the highest
 
Try {
// Get the SVG file ready for the drawing of the perfomance graph
File SVGOutputFile = new File (path, "SVGOnToLogy. svg ");
// File SVGOutputFile = new File ("SVGOnToLogyTest1.svg ");
