As these narratives become more widespread, ensuring their clarity, accuracy, and trustworthiness remains a significant challenge, especially in high-stakes domains such as journalism, public health, and politics. These challenges are compounded by evolving newsroom workflows, fragmented authoring tools, and the rapid rise of generative AI.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EThis dissertation addresses these concerns through a combination of ecosystem analysis, empirical investigation, and interactive system design. It begins with a study of real-world data journalism practices, identifying mismatches between the needs of practitioners and the ways computational tools are typically designed and evaluated in visualization and HCI research. Building on this foundation, I curate and analyze a diverse set of problematic data narratives to develop a multi-dimensional taxonomy of common issues, which are then mapped onto a structured data communication pipeline. To support improved practices, I present two interactive systems. The first, DataWeaver, is an authoring tool that supports composing visualization and text through a bidirectional workflow, helping authors maintain alignment and accuracy during narrative construction. The second, Aletheia, supports fact-checking by connecting data claims to structured evidence using large language models, paired with interactive explanations to guide verification.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003ETogether, these contributions integrate conceptual insight, human-centered design, technological innovation, and empirical evaluation to promote more transparent, accurate, and responsible data communication.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003ESupporting Effective and Trustworthy Data Communication through Interactive Authoring and Assessment of Data-Driven Narratives\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Supporting Effective and Trustworthy Data Communication through Interactive Authoring and Assessment of Data-Driven Narratives"}],"uid":"27707","created_gmt":"2025-07-11 16:27:44","changed_gmt":"2025-07-11 16:28:15","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-07-24T14:30:00-04:00","event_time_end":"2025-07-24T16:30:00-04:00","event_time_end_last":"2025-07-24T16:30:00-04:00","gmt_time_start":"2025-07-24 18:30:00","gmt_time_end":"2025-07-24 20:30:00","gmt_time_end_last":"2025-07-24 20:30:00","rrule":null,"timezone":"America\/New_York"},"location":"TSRB 334 (VIS Lab)","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
