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];
    var board = JXG.JSXGraph.initBoard('jxgbox', {showNavigation:false, showCopyright:true, boundingbox: [-2.4, 8, 13.6, -4]});
    board.containerObj.style.backgroundColor = 'black';
    board.options.label.strokeColor = 'yellow';
    board.suspendUpdate();

    var a = board.createElement('chart', dataArr, 
        {chartStyle:'pie',  
         colors:['#0F408D','#6F1B75','#CA147A','#DA2228','#E8801B','#FCF302','#8DC922','#15993C','#87CCEE','#0092CE'],
         fillOpacity:0.8, center:[5,2], strokeColor:'black', highlightStrokeColor:'black', strokeWidth:4,
         labels:['War games','Sport games', 'Old games','Strategy games', '3D games', 'Puzzle games','Board games', 'I do not play games'],
         highlightColors:['#E46F6A','#F9DF82','#F7FA7B','#B0D990','#69BF8E','#BDDDE4','#92C2DF','#637CB0','#AB91BC','#EB8EBF'],
         highlightOnSector:true, 
         highlightBySize:true,
         gradient:'linear'
        }
    );
    board.unsuspendUpdate();
