Fulham's front three of Ivan Cavaleiro, Anthony Knockaert and Aleksandar Mitrovic is starting to look a formidable attacking threat.
The Cottagers enjoyed 85% possession, 95% pass accuracy and 991 passes to Millwall's 173 in the one-sided affair.
HOW THE HEATMAPS COMPARE
All three were on the scoresheet as the Cottagers saw off Millwall 4-0 for a third win in a row in England's second tier.
Cavaleiro fired home the opener and crossed for Knockaert to make it 2-0 at the end of a move that saw 26 completed passes involving all 11 Fulham players.
Mitrovic got the third from the penalty spot and Cavaleiro added a cool fourth for a Fulham side who enjoyed a remarkable 84 per cent of the possession and completed 934 passes.
Cardiff and Huddersfield, who joined Fulham in dropping out of the Premier League last season, played out a much more even encounter at Cardiff City Stadium.
Trevoh Chalobah cancelled out Joe Ralls' opener, but Neil Warnock's side snatched all three points in the 88th minute through Junior Hoilett's deflected strike.
Sheffield Wednesday went top on Wednesday (AEST) but has dropped three places after wins for three of the early-season pacesetters.
Cardiff City overcame Huddersfield Town in south Wales in a battle of two of last season's Premier League sides, while Jack Butland had a game to forget for Stoke City at Preston North End.
West Brom and Nottingham Forest, meanwhile, each earned a point by virtue of late goals.
