The tool requires a JSON array where each object includes a label, min value, and max value. You can optionally include median, mean, and an array of outlier values. ### Can I customize the appearance of outliers? Yes, you can toggle the visibility of outliers and customize their specific color and point size in the configuration settings. ### What are the available range styles? You can choose between 'Line' (vertical with caps), 'Bar' (filled rectangle), or 'Area' (connected areas) styles to best suit your data. ### Does the tool support different value formats? Yes, you can set the value format to decimal, integer, percentage, or currency to match your specific data type. ### Is the generated chart interactive? The tool generates an HTML-based visualization that supports smooth animations upon loading, which can be configured by duration. ## Related tools - [ECharts Theme Token Extractor](https://elysiatools.com/en/tools/echarts-theme-token-extractor): Extract design tokens — colors, numbers, font sizes and strings — from an ECharts theme JSON and export them straight into your design system. Paste a theme object (the kind registered via echarts.init(dom, themeName)) and the tool walks every leaf, tagging each color (with optional named/rgb → hex normalization), spacing number, font size and string, then emits clean CSS variables, a Tailwind theme.extend config, Style Dictionary tokens.json, or SCSS variables.
