带有加权气泡/气泡大小的气泡智能图

我真的很喜欢气泡智能图：

http://texample.net/tikz/examples/smart-bubbles/

但我想分配自定义节点大小。

更具体地说，我想重新创建这个图形：

气泡图

可以这样做吗？smartdiagram 是不是不合适的工具？有没有类似的工具或者我应该用什么？

只是为了好玩，我写了一些渐近线代码来重现您的示例。图表会自动布局。唯一的输入是标签和数字。

请注意，无论圆圈大小如何，圆圈之间的间距都是相同的。此外，程序逻辑会决定标签是否适合其圆圈，并相应地调整标签位置和颜色。

所有圆圈的面积都是根据数字按比例计算的。但请注意，这些数字加起来不等于 2597，因此蓝色圆圈和红色圆圈的面积之和不等于灰色圆圈的面积。

在此处输入图片描述

    string[] name;

    pen color;

    void operator init(string name, int number, pen color = blue)
    {
        this.name = split(name, " ");
        this.number = number;
        this.color = color;
        this.radius = allRadius * (number / allNumber)^0.5;
        sumRadii += this.radius;
    }

// set angular positions to achieve equal spacing
real spaceBetween = (allCircumference - 2*sumRadii) / causes.length;
causes[0].angularPosition = 180.0;
for (int i = 1; i < causes.length; ++i)
{
    causes[i].angularPosition = causes[i-1].angularPosition -

// Function to draw a label on a picture

    // determine size of a label to see if it will fit in circle

    pair labelSize = size(p, true);

    if (labelSize.x > 2*causes[i].radius ||

    {
        // draw label outside of circle if it won't fit
        add(shift(1.4*center)*p);
    }
    else
    {
        // otherwise draw label inside of circle
        drawLabel(currentpicture, causes[i], center, white);
    }
}

只需更改下面显示的行即可创建不同的图。

int allNumber = 2597;
real allRadius = 1.25; // Changing this size will effect the relative font size 

causes.push(Cause("Heart disease", 611));
causes.push(Cause("Cancer",        585));
causes.push(Cause("Medical error", 251, red));
causes.push(Cause("COPD",          149));
causes.push(Cause("Suicide",        41));
causes.push(Cause("Firearms",       34));
causes.push(Cause("Motor vehicles", 34));
