Conversation connected visualization of items based on a user created list is provided. In some examples, a user may indicate the entry of a list of items to be visualized or user, intent may be inferred from an entered list in an email or similar communication. Connections between the items on the list may be determined and a connected node visualization generated. The visualization may be presented within a user interface in conjunction with the email and users allowed to define or characterize nodes or items in the visualization. Depending on a type of item, different prompts to provide definition/characterization input may be presented. The visualization may be associated with the communication and a conversation to winch the communication belongs. Users may access the visualization through a separate application or through the communication application.
