JSXGraph supports chart plotting. Here are some examples of possible chart types.

        var board = JXG.JSXGraph.initBoard('jxgbox', {originX: 50, originY: 400, unitX: 50, unitY: 50});

        var dataArr = [4,1,3,2,5,7,1.5,2];
        
        // Line chart
        function lineChart() {
            JXG.JSXGraph.freeBoard(board);
            board = JXG.JSXGraph.initBoard('jxgbox', {originX: 50, originY: 500, unitX: 50, unitY: 50});
            board.suspendUpdate();
            var b1axisx = board.createElement('axis', [[0,0], [1,0]], {});
            var b1axisy = board.createElement('axis', [[0,0], [0,1]], {});
            var a = board.createElement('chart', dataArr, {chartStyle:'line',strokeWidth:4,strokeColor:'#0000ff'});
            board.unsuspendUpdate();
        };

        // Line chart with cubic splines
        function splineChart() {
            JXG.JSXGraph.freeBoard(board);
            board = JXG.JSXGraph.initBoard('jxgbox', {originX: 50, originY: 500, unitX: 50, unitY: 50});
            board.suspendUpdate();
