MCP SERVER · OFFICIAL PROJECTTurn a table of numbers into the chart that suits it — one tool per chart type, plus maps and a spreadsheet that becomes a pivot table.
LABSCO SUMMARY
Every chart type is its own tool with its own description of what it is for, so the decision between a column chart and a histogram is made where the data is being described rather than inside a charting library's API. Since the data goes in on the call, anything the model can put in a table it can also plot.
27 generators, one per output type: statistical charts (line, column, bar, area, scatter, histogram, boxplot, violin, radar, funnel, waterfall, sankey, treemap, venn, liquid, pie, word cloud, dual axes), diagrams (flow, mind map, fishbone, organization, network graph), three kinds of map, and a spreadsheet.
npx on your PATH. Each call carries its data inline, so nothing connects to a database — the numbers come from the conversation.
One command — npx -y @antv/mcp-server-chart
USE CASES
Hand over the series and get a line, area or column chart with titled axes and a theme — the version that goes in the deck rather than the one in your notebook.
A horizontal bar chart handles long category names that a column chart squashes, and grouping or stacking is a parameter rather than a rebuild.
Draw it as a flow diagram or a mind map, so the shape of the thing is on the page instead of in four paragraphs of prose.
A fishbone diagram puts the causes around the problem by category; a Sankey shows where the volume is actually going when the answer is about flow.
Districts for coverage by region, pins for individual locations with popups, and a path when the point is the route rather than the places.
Pass the tabular data with rows and values and it renders as a pivot table rather than a flat grid, which is what a summary usually needs to be.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
generate_area_chartGenerate a area chart to show data trends under continuous independent variables and observe the overall data trend, such as, displacement = velocity (average or instantaneous) × time: s = v × t. If the x-axis is time (t) and the y-axis is velocity (v) at each moment, an area chart allows you to observe the trend of velocity over time and infer the distance traveled by the area's size.
generate_bar_chartGenerate a horizontal bar chart to show data for numerical comparisons among different categories, such as, comparing categorical data and for horizontal comparisons.
generate_boxplot_chartGenerate a boxplot chart to show data for statistical summaries among different categories, such as, comparing the distribution of data points across categories.
generate_column_chartGenerate a column chart, which are best for comparing categorical data, such as, when values are close, column charts are preferable because our eyes are better at judging height than other visual elements like area or angles.
generate_district_mapGenerates regional distribution maps, which are usually used to show the administrative divisions and coverage of a dataset. It is not suitable for showing the distribution of specific locations, such as urban administrative divisions, GDP distribution maps of provinces and cities across the country, etc. This tool is limited to generating data maps within China.
generate_dual_axes_chartGenerate a dual axes chart which is a combination chart that integrates two different chart types, typically combining a bar chart with a line chart to display both the trend and comparison of data, such as, the trend of sales and profit over time.
generate_fishbone_diagramGenerate a fishbone diagram chart to uses a fish skeleton, like structure to display the causes or effects of a core problem, with the problem as the fish head and the causes/effects as the fish bones. It suits problems that can be split into multiple related factors.
generate_flow_diagramGenerate a flow diagram chart to show the steps and decision points of a process or system, such as, scenarios requiring linear process presentation.
generate_funnel_chartGenerate a funnel chart to visualize the progressive reduction of data as it passes through stages, such as, the conversion rates of users from visiting a website to completing a purchase.
generate_histogram_chartGenerate a histogram chart to show the frequency of data points within a certain range. It can observe data distribution, such as, normal and skewed distributions, and identify data concentration areas and extreme points.
generate_line_chartGenerate a line chart to show trends over time, such as, the ratio of Apple computer sales to Apple's profits changed from 2000 to 2016.
generate_liquid_chartGenerate a liquid chart to visualize a single value as a percentage, such as, the current occupancy rate of a reservoir or the completion percentage of a project.
generate_mind_mapGenerate a mind map chart to organizes and presents information in a hierarchical structure with branches radiating from a central topic, such as, a diagram showing the relationship between a main topic and its subtopics.
generate_network_graphGenerate a network graph chart to show relationships (edges) between entities (nodes), such as, relationships between people in social networks.
generate_organization_chartGenerate an organization chart to visualize the hierarchical structure of an organization, such as, a diagram showing the relationship between a CEO and their direct reports.
generate_path_mapGenerate a route map to display the user's planned route, such as travel guide routes.
generate_pie_chartGenerate a pie chart to show the proportion of parts, such as, market share and budget allocation.
generate_pin_mapGenerate a point map to display the location and distribution of point data on the map, such as the location distribution of attractions, hospitals, supermarkets, etc.
generate_radar_chartGenerate a radar chart to display multidimensional data (four dimensions or more), such as, evaluate Huawei and Apple phones in terms of five dimensions: ease of use, functionality, camera, benchmark scores, and battery life.
generate_sankey_chartGenerate a sankey chart to visualize the flow of data between different stages or categories, such as, the user journey from landing on a page to completing a purchase.
generate_scatter_chartGenerate a scatter chart to show the relationship between two variables, helps discover their relationship or trends, such as, the strength of correlation, data distribution patterns.
generate_spreadsheetGenerate a spreadsheet or pivot table for displaying tabular data. When 'rows' or 'values' fields are provided, it renders as a pivot table (cross-tabulation); otherwise, it renders as a regular table. Useful for displaying structured data, comparing values across categories, and creating data summaries.
generate_treemap_chartGenerate a treemap chart to display hierarchical data and can intuitively show comparisons between items at the same level, such as, show disk space usage with treemap.
generate_venn_chartGenerate a Venn diagram to visualize the relationships between different sets, showing how they intersect and overlap, such as the commonalities and differences between various groups.
generate_violin_chartGenerate a violin chart to show data for statistical summaries among different categories, such as, comparing the distribution of data points across categories.
generate_waterfall_chartGenerate a waterfall chart to visualize the cumulative effect of sequentially introduced positive or negative values, such as showing how an initial value is affected by a series of intermediate positive or negative values leading to a final result. Waterfall charts are ideal for financial analysis, budget tracking, profit and loss statements, and understanding the composition of changes over time or categories.
generate_word_cloud_chartGenerate a word cloud chart to show word frequency or weight through text size variation, such as, analyzing common words in social media, reviews, or feedback.
BEFORE YOU INSTALL
27 tools when we connected. DISABLED_TOOLS removes tools by name, and a private deployment via VIS_REQUEST_SERVER loses the three geographic tools: district-map, path-map and pin-map.
