在D3中对SVG元素进行分组

标签： javascript d3.js svg

我在我的D3中实施了一辆车。信息图形。然而;它在我的容器中相当大，而且没有动画。我想将这些元素分组，然后缩小它，＆amp;最后动画它以循环或连续移动。基本上可以让汽车小得多，它可以自由地在页面周围动画。

d3.select('#dataVizContainer svg').append("rect")
    .attr('id', 'rect1')
    .attr("fill", "transparent")
    .attr("stroke", "#99C863")
    .style('stroke-width', '10px')
    .attr("width", 210)
    .attr("height", 130)
    .attr("opacity", 0)
    ;

d3.select('#rect1')
    .transition()
    .attr("x", 70)
    .attr("y", 10)
    .attr('rx', 150)
    .attr("fill", "transparent")

    .delay(2000)
    .duration(12000)
    .attr("opacity", 1);


d3.select('#dataVizContainer svg').append('line').attr('id', 'line')
    .attr('x1', 145).attr('y1', 10).attr('x2', 145).attr('y2', 80)
    .style('stroke', '#99C863').style('stroke-width', '10px').attr("opacity", 0);
//Animation
d3.select('#line')
    .transition()
    .delay(2000)
    .duration(12000)
    .attr("opacity", 1);

d3.select('#dataVizContainer svg').append('line').attr('id', 'line2')
    .attr('x1', 215).attr('y1', 10).attr('x2', 215).attr('y2', 80)
    .style('stroke', '#99C863').style('stroke-width', '10px').attr("opacity", 0);
//Animation
d3.select('#line2')
    .transition()
    .delay(2000)
    .duration(12000)
    .attr("opacity", 1);

    .attr("stroke", "crimson")
    .style('stroke-width', '10px')
    .attr("width", 40)
    .attr("height", 20)
    .attr("opacity", 0)
    ;
d3.select('#rect3')
    .transition()
    .attr("x", 0)
    .attr("y", 110)

    .delay(2000)

在这里你去：我把你的车放在一个svg组中并稍微更改了你的代码，最后我让你的车移动你也可以添加所有类型的转换到汽车元素，如：https://developer.mozilla.org/fr/docs/Web/CSS/transform
