Only an example of how I personally generally do data analysis:
Analysis of the development of changes in the network advertising in 2010-2016, for example, can be these ideas: 10-16 ad revenue of the The specific situation and year-on-year situation (dual-axis chart), advertising is mainly concentrated in the distribution of which places (data map), advertising is concentrated in which industries (pie charts, ring charts) and so on, the different data dimensions require different charts, these charts can be done in BDP Personal Edition and EXCEL, depending on whether you have the data.
In fact, I think the main thing is not to predict what, but first have the data, and then analyze according to their own needs. I hope the owner to adopt.
