[Purpose/significance] Data storytelling is the process of building a narrative based on data and conveyingdata insights. There are many technologies of related research areas can support implementation of data storytelling.This study attempts to sort out the key technologies of the process of data story narration and design a technical framework. [Method / process] This paper discusses two ways of data story narration firstly, namely visual narrative and textnarrative. Then the technical framework of data story narration is built and its application in data storytelling is described in detail. Finally, the development characteristics of related techniques and tools of data storytelling are discussed. [Result/conclusion] In this paper, it is proposed that the process of data storytelling includes the generation ofdata story and the narrative of data story. In the narrative process, a variety of related technologies are useful, while therelevant technologies in the generation process are lacking. In addition, six development characteristics of data storynarration related technologies are summarized.
