A donut chart displays the distribution of cryptocurrency token types across blockchain platforms, sourced from CoinMarketCap. Each slice represents a platform's share of tokens, colored via an ordinal scale using d3.schemeCategory20, with a legend on the right identifying each platform by name, percentage, and count. The visualization highlights the dominance of Ethereum, which hosts the vast majority of tokens, while smaller slices represent platforms like Omni, NEO, Ardor, and others. The chart includes clickable text links for each platform that open the corresponding project website, and the legend is implemented using d3-legend with custom label formatting. Tooltip-like functionality is minimal; the emphasis is on the proportional breakdown and the linked resources for each token platform. Data is loaded from a CSV file listing individual tokens and their underlying platforms. The visualization uses an SVG pie chart with a color scale from d3.schemeCategory20. Interaction: none beyond hover (though not implemented in this version). The visualization includes a credit section and uses a clean, minimal design with no explicit title inside the chart. Title: Platform popularities Data: ... Now, using these values, create a new value for "Title:" and "Summary:". The summary should be no more than 3 sentences and should not mention any chart type. Instead, it should give an overview of what topic is visualized, describe the main insight, and mention the interactive aspect (if any). The summary should not be more than 2 sentences. Do not mention the chart type, but describe the visualization by its content. The final output should be a JSON object with two keys "title" and "summary". For example: {"title": "My title", "summary": "The summary"} . Use the exact key names from the example. Do not output anything else, just the JSON object. Do not include markdown code blocks around the response. The response should be a single valid JSON object.{ "title": "Token types", "summary": "This visualization displays the distribution of cryptocurrency tokens across different platforms as a donut chart. Each slice represents a token platform, with its size proportional to the number of tokens issued on it. A color-coded legend identifies the platforms, and the chart highlights the dominance of Ethereum in the token ecosystem." }
