There are `$= dv.pages().length` notes in this vault.
 - my notes contain :
     - `$= dv.pages("#maths").length` #s/maths notes
         - `$= dv.pages("#maths/algèbre").length` #s/maths/algèbre notes
     - `$= dv.pages("#science").length` #s/science notes
     - `$= dv.pages("#politique").length` #s/politique notes

Statistics :
 - :obs_links_going_out: average of `$= Math.round(eval(dv.pages("").file.map((f)=>f.outlinks.length).join("+")) / (dv.pages("").file.length)*100)/100` outlinks per note
 - :obs_links_coming_in: average of `$= Math.round(eval(dv.pages("").file.map((f)=>f.inlinks.length).join("+")) / (dv.pages("").file.length)*100)/100` inlinks per note
