如何使用GNU R创建一个分类气泡图,类似于系统映射研究中使用的(见下文)？

编辑:好的,这是我到目前为止所尝试的.首先,我的数据集(Var1转到x轴,Var2转到y轴):

                         Var1                      Var2 count

   import matplotlib.pyplot as plt
    import numpy as np
    # data
    x=["IEEE", "Elsevier", "Others"]
    y=[7, 6, 2]
    import seaborn as sns
    plt.legend()
    plt.scatter(x, y, s=300, c="blue", alpha=0.4, linewidth=3)
    plt.ylabel("No. of Papers")
    plt.figure(figsize=(10, 4)) 

我想制作一个如图所示的图表。我不确定如何提供期刊和会议类别的数据。（目前，我只包括一个）。另外，我不确定如何为每个类别添加不同的颜色。
