Office recommends version 20 16 or above, because Excel has the function of drawing maps after version 2016, that is, drawing maps according to the latitude and longitude provided, and then drawing heat maps, histograms, etc. On the map, this is much better than arcgis. Words make no difference.

Then my own visio is 20 10. I feel that there is no difference between the old and new versions, except that there are several patterns, and the extra ones are basically unnecessary.

In addition, modeling competitions do not always require drawing. In fact, if the subject has time, he can try python and R, and draw some pictures such as nightingale rose (the name sounds awesome). Very convenient, the code can be found online. If you have time, you can prepare before the game (but not necessarily, it is best to use it).
