Display a RDF metadata near related reactions

As a **User**, I want **to see text and images from metadata** near the reactions to which this metadata belongs, so that I can have a comprehensive view of the reactions with their related information.

**Acceptance Criteria:**

1. A user should be able to view text and images from metadata associated with a reaction. This metadata should be displayed near the reaction it pertains to on the canvas.
2. The application should provide a clear and legible display of the text from metadata. The text should not overlap with the reaction or other elements on the canvas.
3. Images from metadata should be displayed in a size that is clearly visible but does not obstruct or overwhelm the reaction diagram.
_4. The application should handle the display of multiple metadata entries for a single reaction, ensuring that all metadata is visible and distinguishable._
_5. If there are any issues or errors during the display of metadata, the application should display an appropriate error message and guide the user to resolve the issue._
