## About hGraph [#about-hgraph]

hGraph is a typed, bi-temporal knowledge graph. It records when a fact is true and when that fact is known, so changes can be traced across both time axes. It implements SemType’s data model within the hgres stack.

Visit [hGraph on hgres.org](https://hgres.org/hgraph) for the project’s technical documentation.

## Logo and icon [#logo-and-icon]

The blue gradient “h” is the compact icon. The full hGraph wordmark already includes this symbol as its first letter; use the complete artwork without adding a second icon beside it.

Use the dark lettering on light backgrounds and the light lettering on dark backgrounds. The supplied SVGs retain their detail at any size.

## Writing the name [#writing-the-name]

Use **hGraph**, with a lowercase “h” and a capital “G”. Introduce it as part of [hgres](/brands/hgres) when the relationship is not already clear.

## Downloads [#downloads]

Use the supplied artwork without redrawing, stretching, or adding effects. Keep enough clear space for the mark to remain legible.
