The user wants a single index.html with an inline script that uses d3.min.js via src. First, check the directory.

Create index.html with a force graph. About 40 nodes, around 5 clusters. Programmatically generate the sample nodes/links, but "define the sample nodes and links inline" — hardcode them. Either write a generator-style inline definition, or explicitly list them. Easier approach: define the cluster names and node names inline in an array, and construct the links. Hardcoding 40 nodes and ~60 links is a lot but that's fine. Let's go with a compact inline definition.

One concern: `Math.random()` inside the link construction makes the ring non-deterministic — within acceptable range, but a deterministic method is preferable. Also, the cluster force is a custom function that gets called with alpha as an argument — d3 calls forces with alpha, so this will work.

Also, there are a few messy filters in the inter-cluster list, including weird entries like [1,34] ("iOS App -> iOS App?" with the comment fixed below, but actually 1=Vue, 34=iOS App — no problem), [21,31] Redis->Load Balancer, [27,37] — 27=Elasticsearch, 37=Android App (the comment says CDN but the indices are different), [29,36] = Mobile Biometrics? Let's verify the indices:

Cluster 0: 0 React, 1 Vue, 2 Svelte, 3 CSS, 4 Webpack, 5 Vite, 6 Router, 7 Redux, 8 TS, 9 Vitest
Cluster 1: 10 API Gateway, 11 Auth, 12 Users, 13 Orders, 14 Payments, 15 Search, 16 Notif, 17 Rate Limiter, 18 Config, 19 Logger
Cluster 2: 20 Postgres, 21 Redis, 22 Kafka, 23 Spark, 24 Airflow, 25 dbt, 26 Snowflake, 27 Elasticsearch, 28 Feature Store, 29 ETL Worker
Cluster 3: 30 K8s, 31 Docker, 32 Terraform, 33 CI Pipeline, 34 Monitoring, 35 Alerting, 36 LB, 37 CDN, 38 Object Storage, 39 Secrets
Cluster 4: 40 iOS, 41 Android, 42 RN, 43 Push, 44 Offline, 45 Biometrics

Oops! I was miscounting — I assumed 9 nodes for clusters 1–3, but actually cluster 1 has 10 (10–19), and cluster 2 is 20–29, cluster 3 is 30–39, and cluster 4 is 40–45. The total becomes 46 nodes, not 40! Let me count: 10+10+10+10+6 = 46. Hmm, "about 40" — 46 is close, but the hardcoded inter-cluster indices are wrong: e.g. [1,34] is Vue→Monitoring, [33,36] is CI Pipeline→Load Balancer, [36,11] is LB→Auth... the comments don't match, and some pairs might be intra-cluster links (that's fine) or strange bridges. Also [38,16] appears twice and gets removed by the dedup filter. Furthermore, the first filter is a meaningless expression. Let's clean this up properly: reduce cluster sizes to get to about 40 (e.g. 10/8/8/8/6 = 40), and define clean inter-cluster links with correct indices.

Let me rewrite the data section. Clusters:
- Frontend (10): React, Vue, Svelte, CSS, Webpack, Vite, Router, Redux, TS, Vitest → indices 0–9
- Backend (8): API Gateway(10), Auth(11), Users(12), Orders(13), Payments(14), Search(15), Notif(16), Logger(17)
- Data (8): Postgres(18), Redis(19), Kafka(20), Spark(21), Airflow(22), dbt(23), Snowflake(24), Elasticsearch(25)
- Infra (8): Kubernetes(26), Docker(27), Terraform(28), CI Pipeline(29), Monitoring(30), Alerting(31), Load Balancer(32), CDN(33)
- Mobile (6): iOS App(34), Android App(35), React Native(36), Push Svc(37), Offline Cache(38), Biometrics(39)

Total 40.

Inter-cluster bridges:
[0,10] React→API GW, [1,10] Vue→API GW, [12,18] Users→Postgres, [11,19] Auth→Redis, [14,20] Payments→Kafka, [15,25] Search→Elasticsearch, [16,20] Notif→Kafka, [17,26] Logger→K8s, [10,26] API GW→K8s, [10,32] API GW→LB, [24,21] Snowflake→Spark, [22,28] Airflow→Terraform, [30,24] Monitoring→Snowflake, [34,11] iOS→Auth, [35,11] Android→Auth, [36,34] RN→iOS, [36,35] RN→Android, [0,36] React→RN, [37,20] Push→Kafka, [38,34]? offline cache→iOS is intra-cluster (38 is mobile). [38,19] Offline→Redis, [39,11] Biometrics→Auth, [33,0] CDN→React, [31,20] Alerting→Kafka, [27,26] Docker→K8s is intra-cluster (both infra, no problem but already covered by the hub). [32,26] LB→K8s intra-cluster. [29,0] CI→Vitest? [29,9] CI→Vitest, no problem.

Also, remove Math.random for determinism, and remove the ridiculous filter. Extra intra-cluster links: keep the deterministic list and update the indices: [[3,4],[5,7],[8,9],[13,14],[15,16],[21,24],[22,23],[31,32],[37,39]].

Let me rewrite the relevant part of the file with an edit. Actually, it's easier to rewrite the whole script section of the file with write.

Verify with node: simulate the data logic and confirm the number of nodes/links, and that there are no out-of-range or self-referential indices. Quick check.

Typo in my verification script: `map(i=>[i,new Set()]))` — missing `)`. Correction: `new Map([...ids].map(i=>[i,new Set()]))`.

"const" inside "eval" in a module context — does "const" declared inside "eval" in non-strict mode stay within the eval scope? Actually, in non-strict "indirect eval", function declarations leak out, but "const" stays inside the eval's block scope. Use "indirect eval" that returns a value, or just replace it with "var". An easier way: write the snippet to a temporary file with the same content, add "console.log", and then run it.

All verified: 40 nodes, 88 links, all valid and connected, loading only the local d3.min.js, no external URLs. Done.
