Python development [module]: CSV file data visualization,CSV Module 1. CSV file format To store data in a text file, the simplest way is to write data into a file as a series of comma-separated values (CSV). Such a file becomes a CSV file, as shown below: AKDT,Max TemperatureF,Mean TemperatureF,Min TemperatureF,Max Dew

with the GGPLOT2 in the R language, it seems that two packages are used and the likelihood is developed by the same person! The original author also said on GITHUB that the PYTHON library will no longer be updated! However, ggplot2 is really a drawing artifact, which is almost the only reason I am still using the R language. Therefore, matplotlib is required no matter which library you want to use. Although his syntax is complex, he is flexible. you can draw almost any image you want. Here we
