            "team": "d",
            "cycleTime": 2,
            "effort": 2,
            "count": 5,
            "priority": "low"
        }, {"team": "d", "cycleTime": 3, "effort": 3, "count": 8, "priority": "medium"}, {
            "team": "d",
            "cycleTime": 4,
            "effort": 4,
            "count": 3,
            "priority": "high"
        }, {"team": "l", "cycleTime": 2, "effort": 1, "count": 1, "priority": "low"}, {
            "team": "l",
            "cycleTime": 3,
            "effort": 2,
            "count": 5,
            "priority": "low"
        }, {"team": "l", "cycleTime": 4, "effort": 3, "count": 8, "priority": "medium"}, {
            "team": "l",
            "cycleTime": 5,
            "effort": 4,
            "count": 3,
            "priority": "high"
        },
        {"team": "k", "cycleTime": 2, "effort": 4, "count": 1, "priority": "low"}, {
            "team": "k",
            "cycleTime": 3,
            "effort": 5,
            "count": 5,
            "priority": "low"
        }, {"team": "k", "cycleTime": 4, "effort": 6, "count": 8, "priority": "medium"}, {
            "team": "k",
            "cycleTime": 5,
            "effort": 8,
            "count": 3,
            "priority": "high"
        }];
var chart = new tauCharts.Chart({
            data: defData,
            type: 'horizontalBar',           
            x: 'effort',
            y: 'team',
            color:'priority'
        });
chart.renderTo('#bar');
