A pie chart with highlight on the whole sector, enlarging labels on highlight and a gradient fill.

JavaScript code to produce this chart

    var dataArr = [30,16,14,10,10,8,6,6,4,4];
    var board = JXG.JSXGraph.initBoard('jxgbox', {showNavigation:false, showCopyright:true, originX: 120, originY: 400, unitX: 50, unitY: 50});
    board.containerObj.style.backgroundColor = 'black';
    board.suspendUpdate();

    var a = board.createElement('chart', dataArr, 
        {chartStyle:'pie',  
         colorArray:['#0F408D','#6F1B75','#CA147A','#DA2228','#E8801B','#FCF302','#8DC922','#15993C','#87CCEE','#0092CE'],
         fillOpacity:0.8, center:[5,2], strokeColor:'black', highlightStrokeColor:'black', strokeWidth:4,
         labelArray:['Ruby','JavaScript', 'Shell','Python', 'PHP', 'C','Perl', 'C++', 'Java', 'Flash'],
         highlightColorArray:['#E46F6A','#F9DF82','#F7FA7B','#B0D990','#69BF8E','#BDDDE4','#92C2DF','#637CB0','#AB91BC','#EB8EBF'],
         highlightOnSector:true, 
         highlightBySize:true,
         //gradient:'linear'
        }
    );
    board.unsuspendUpdate();
