In July 2025, this developer enhanced the Earthquake_Landslide bar chart within the gis502/xian_vue repository, focusing on data visualization for seismic impact analysis. They introduced a custom InclinedRoofColumn shape with a gradient fill using ECharts and Vue, improving the chart’s visual clarity and distinction between data points. Labels were repositioned above each bar to facilitate easier data scanning, and the overall chart configuration was refined for better scalability across devices and dashboards. The work demonstrated a solid grasp of frontend development and JavaScript, resulting in a more effective tool for stakeholders to interpret and act on seismic data insights.
