I've read somewhere on the Internet that heating graphite at 4200°K at a sufficiently high pressure would turn it into diamond.
This chart seems to support this idea:
Is that doable industrially?

It has been done since 1954 and has been a commercial success for some time. Many products now have diamond-like coatings, produced comparatively inexpensively through vapor deposition without need for high pressure.
BTW, in English "burning" means to set on fire, oxidize; I believe you mean "heating graphite", and, as your graph shows, pressure is needed as well as heat.
You want to heat graphite at high pressure, not burn it - but yes, high-T, high-p will work.

There is a rather lengthy and informative Wikipedia article for synthetic diamond that illustrates (in part) the use of this process - HPHT, for "high pressure, high temperature"(using a high-purity source of carbon, not necessarily graphite) in industry. Note that there are several industrial processes mentioned in addition to HPHT.
