Bottom 见 — the indexing radical, simplified from 見, picturing an eye on legs (a person looking). 览 means to view broadly, take in a sweep of sights, so the 'see' radical is core. Compounds: 浏览 browse, 游览 tour, 阅览 peruse.
Top derived from 监 in a heavily contracted 5-stroke form (standalone 监 has 10 strokes, here fused). Pictured a person looking into a water bowl used as a mirror, hence 'to oversee.' Supplies the sound — jiān drifting to lǎn — and the 'survey, look over' meaning.
