How can I convert my observations to graphic form, which can be used in article.
That really depends on what you want to show with it.
Broadly speaking, you can download a CSV of all your observation info (but not the images), and use GIS or other software to organize, process, and display it.
ArcGIS (premium software) and QGIS (free, open source software) are two of the most commonly used GIS packages for this sort of thing, but not the only ones.
You can also display downloaded data in Google Earth, although you may want to edit it with Excel or a similar program first if you only need a subset of the observations.
