chart.animate({
    data_4

- duplicate the Dimension in the Color channel onto the Y-axis
- null the Label channel
chart.animate({
    config: {
        "channels": {
            "color": "Country",
            "size": [
                "Year",
                "Value 2 (+)"
            ],
            "label": "Year"
        }
    }
});
