Hover box overlapping point/cursor

With plotly express, when using hover_data, the hover box sometimes covers the point for which it is shown (depending on the size of the hover box). It would be good if this could get avoided by shifting the box. In many cases, it is clear before showing the plot, in which direction the hoever box could get shifted to better avoid this, so even if the javascript cannot figure this out automatically it would be good to allow something like "hover_box_delta_x", "hover_box_delta_y" to shift the box that many pixels to the right (if negative, to the left), for example.

When the box completely covers the cursor and the point it is shown for it is very hard to put the information in context and even harder to show the information for another point, because neighbouring points are not visible at all.

首先跟踪与 plotly express 和 hover_data 一起使用的 JavaScript 悬停处理，重点关注悬停框相对于其点和光标的位置。完成的标准是：在可能的情况下，悬停框不会遮挡选中的点；当自动定位无法确定更好的方向时，支持所提议的水平和垂直像素偏移。
