The source for these charts is the MIT Harvard's Observatory of Economic Complexity, a US source of debatable reliability when it comes to Iran, a country systematically demonized in America.
As user Indos indicated, these are only relating to exports. In Iran's case, it's true that the oil sector still represents a significant part of hard currency incomes, however this figure now stands way below 79% according to official statistics (it used to be on that level some twenty years ago). When it comes to the government's budget, oil exports now make up for less than 50% of revenues.
So these figures do not offer an accurate representation of Iran's economic diversification, which is surely superior to the likes of Saudi Arabia.

This chart is interesting, but concerning Iran there's a specific issue which doesn't seem to have been taken into account, namely the fact the Iranian currency has been experiencing unusual and lasting depreciation against the US dollar. Therefore, the value shown here (especially if nominal exchange rate was used) won't appropriately mirror Iran's effective manufacturing volume.
Most of the non-petroleum commodities manufactured in Iran are destined to the domestic market of over 84 million people, and then to immediate neighbors such as Iraq, Afghanistan etc.
To imagine that Saudi Arabia's industrial output is nearly twice as high as Iran's would definitely be misleading. Iran is much more industrialized. I'd suggest zooming in on large Iranian cities using some online satellite imaging service to realize the staggering amount of factories there are.
