The SVG <defs> <symbols>  element is used to predefine an element so that it can be reused in an SVG image

<svgxmlns="http://www.w3.org/2000/svg" width="500"height="100">

     < symbol id = "shape2" >          < circle cx = "25" cy = "25" r = "25" style = "fill:#bf55ec;" />      </ symbol >      < use xlink:href = "#shape2" x = "50" y = "25" /> </ svg > can also be referenced using URLs

 <defs> <lineargradient id= "LinearGradient" > <stop offset= "0%" stop-color= "#f00"/&G            T <stop offset= "stop-color=" #f60 "/> </linearGradient> </defs>/Apply linear gradient <rect x=" "Y=" "width=" "height=" stroke= "Orange" stroke-width= "5" fill= "url (#linearGradient)"/> 
 or 
 < Defs><clippath id= "highcharts-1" ><rect x= "0" y= "0" width= "814" height= "247" ></rect></ Clippath></defs> 
 <g class= "highcharts-series highcharts-tracker" visibility= "visible" zIndex= "0.1" transform= "Translate (0,0) scale (1 1)" style= "" clip-path= "url (#highcharts-1)" ></G> 

  <g class= "highcharts-series highcharts-tracker" visibility= "visible" zIndex= "0.1" transform= "Translate (70,80) scale (1 1)" style= "" clip-path= "url (#highcharts-1)" ></G>  
   If the scale y-axis shrinks to the original 0.6 times scale (1 0.6) then the resulting graph is the graphic height 247* (1-0.6) + Original y-axis value = 179.2   
  <g class= " Highcharts-series highcharts-tracker "visibility=" visible "zindex=" 0.1 "transform=" translate (70,179.2) scale (1 0.6) " style= "clip-path=" url (#highcharts-1) "></G> 
 
: Translate (70,80) scale (1 1) =======" Translate ( 70,179.2) scale (1 0.6) 

The Text-anchor property can be used as justification for using
transform= "Translate (0,0) rotate (rotation angle, position x after rotation, y)"
