The application relates to a text rendering method and device, a storage medium and an electronic device. The method comprises the following steps: when reading characters of a text to be rendered from a memory, determining the amount of the characters in the memory; determining a rendering delay of the characters of the text to be rendered according to the amount of the characters; and when displaying the text to be rendered on a display screen, rendering the characters of the text to be rendered at a rendering speed matched with the rendering delay. The application solves the technical problem that the streaming display speed of data is slow when streaming data output by an LLM is rendered to a screen, thereby affecting the user experience.

This invention relates to the field of traffic system analysis technology, and more particularly to a method, system, device, and storage medium for optimizing complex WebGIS front-ends for traffic system analysis. The method constructs a WebGIS front-end data optimization framework for traffic system analysis, uniformly schedules geospatial data, and implements targeted optimizations at the levels of data transmission, data organization, data caching, and data rendering. It builds a dynamic component-based architecture based on the Vue.js progressive framework, enabling dynamic configuration and generation of traffic analysis functions through JSON configuration files. Simultaneously, it extracts the mapping requirements of traffic system analysis tasks, establishes a mapping relationship between general traffic symbols and preset mapping templates, and constructs a dual-engine rendering adaptation model based on style expressions and style container objects to achieve efficient visualization output of analysis results. This invention can improve the operating efficiency, scalability, and maintainability of WebGIS front-ends in traffic system analysis scenarios.
