The Chemical Structure Renderer plugin allows you to visualize chemical compounds directly within Obsidian notes by rendering SMILES notation as graphical chemical structures. By inserting SMILES strings into a code block tagged with 'smiles', the plugin generates and displays the corresponding molecular structures in the live preview mode. The plugin is powered by Ketcher and Indigo services, offering customizable settings for the rendered images and the ability to use a personal rendering server. This tool is ideal for users in fields like chemistry or biology who need to incorporate chemical structures into their notes seamlessly.
