These are real renders from the API with the example values in the table below. Switch the size above: the same template lays itself out for all 6 sizes — send size or sizes with the request.
For shops, apps, venues and SaaS review pages showing what all reviews add up to (one review is testimonial-stars). Give the average and count or let the card work them out from the distribution. Stars are clipped to the average and clamped to 0–5; a missing picture becomes a monogram tile. Wide and square frames put the score beside the histogram; vertical ones centre a big picture, the score and the bars under each other.
Fields
Every field is optional. Long text shrinks to fit instead of overflowing; an image field takes a public URL that we fetch on our side.
