用于屏幕坐标和频率字典的Python热图

只是为了好玩，我正在尝试编写鼠标跟踪脚本，我的基本部分正在工作，但是我绝对不喜欢热图。

我最初的代码是通过PIL保存图像（只是检查它是否工作），这很好，但显然它只是单个点。然后，我尝试实现自己的热图，但是发现要花费半年以上的时间才能完成一些真正基本的操作，因此也无法正常工作。

我一直在尝试使用matplotlib的其他示例，但我刚刚意识到“热图”在这种情况下的含义有所不同。

It's not not working, but it's also definitely not the result I was hoping to see. I'm wondering if anyone knows how I'd actually go about getting the other type of heatmap, where you get the blobs of heat? I've been googling a bunch of terms but it seems to lead back to the same 3 or so SO questions.

The data is stored in a dictionary of {(x, y): frequency}, so to get the result above I used this code (matplotlib part got from Plotting a 2D heatmap with Matplotlib):

import matplotlib.pyplot as plt

resolution = (1920, 1080)

total = []
for y in range(resolution[1]):
    row = []
    for x in range(resolution[0]):
        try:
            row.append(data[(x, y)])
        except KeyError:
            row.append(0)
    total.append(row)

plt.imshow(total, cmap='hot', interpolation='nearest')
plt.show()

The speed of that doesn't matter so much as it'll be done separately to the tracking, I'd just like something that'd initially work.

Edit: Just to clear it up a little (apologies if it wasn't clear), something like this is what I'd like:
