    var chart = c3.generate({
    data: {
        columns: [
            ['data1', 30],
            ['data2', 130],
            ['data3', 130]

        ],
        type: 'bar'
    },
    bar: {
        width: 50,

    }
});

    Here we have shown datas in three groups into data1,data2 and data3 but the graphs are attached without any spaces like in images

    How can we add the space in between the bars?

    Reset to default 9 
    var chart = c3.generate({
    data: {
        columns: [
            ['data1', 30],
            ['data2', 130],
            ['data3', 130]

        ],
        type: 'bar'
    },
    bar: {
        space: 0.25
    }
});

    Thanks to @zohaib-ijaz's ment. I came up with:

    d3.selectAll(".c3-target-nameofyourclass")
    .selectAll(".c3-bar")
    .attr("transform", "translate(-5, 0)");

    to move the bars from column "nameofyourclass" 5 pixels to the left.

    here is the way in c3 to achieve what you want. you are not able to creat space between different columns as per my knowledge.

    var chart = c3.generate({
      data: {
        columns: [
            ['barData', 30, 130, 130]
        ],
         type: 'bar'
    },
    axis: {
        x: {
            type: 'category',
            categories: ['data1', 'data2', 'data3']
        }
    },
    bar: {
        width: 50,
    }

});

    Use this

    bar: {
    width: {
        ratio: 0.5 // this makes bar width 50% of length between ticks
    }
