Fix first benchmark image to use raw values instead of floor division

The original bench1() function used floor division by 10,000,000 which caused
all Doublets values (71-1465 ns) to become 1 after clamping, making all bars
appear the same length.

Changed to use raw values directly (matching bench2's approach but without log
scale). Now bars correctly reflect actual time differences - Neo4j operations
show their true longer times while Doublets values are so small they appear
minimal (as expected and noted in README: "for doublets just minimum value is
shown, otherwise it will be not present on the graph").

Fixes #7
