We need to produce an article with no title, just body, 1500+ characters (words? likely characters). Must be 6-8 paragraphs, each 150-250 characters (or words?). Likely characters. Must be 1500+ characters total. No title. Must discuss "excel怎么做区间分布图". Must be natural, conversational, avoid AI clichés. Avoid listed forbidden words. Also avoid the transition words: 、. Also avoid 开头禁用: 、. Also avoid transition words list. Use short sentences, active voice, etc.

We need 6-8 paragraphs, each 150-250 characters. Let's aim for 7 paragraphs, each about 220 characters. 7*220=1540 characters, good.

We must not use title. Just output the body.

We must not use any of the forbidden transition words. Also avoid "、". Also avoid "" etc. Use natural transitions like "然后" maybe okay? Not listed but maybe okay. Safer to avoid any transition words that are explicitly banned. They only listed those specific ones. We can use "然后" but better to avoid any that might be considered transition? It's not listed. But to be safe, we can use simple sentences.

We need to ensure each paragraph is 150-250 Chinese characters. Let's craft paragraphs.

Paragraph length count: need to approximate characters. We'll write around 200 characters each.

Paragraph 1: introduce the topic, echo title.

Paragraph 2: explain why interval distribution chart matters.

Paragraph 3: prepare data.

Paragraph 4: create chart steps.

Paragraph 5: customize chart.

Paragraph 6: common pitfalls.

Paragraph 7: concluding view.

Make sure not to use "". Use active voice.

Now craft paragraphs with about 200 characters each.

Let's draft paragraph 1 (~200 characters):

"Excel里有很多图表能帮我们快速看懂数据，今天聊聊怎么用Excel做区间分布图。它能把一堆数字划分进几个区间，一目了然地展示每个区间的数量。只要三步，就能把枯燥的数据变成直观的可视化，适合在报表里直接使用。"

Count characters: Let's count roughly. Chinese characters count each. Let's count manually:

Excel里有很多图表能帮我们快速看懂数据， (14?) Let's approximate length ~150? Might be less. Need 150-250 characters per paragraph. Let's aim for ~200 characters.

Let's count precisely: I'll write with markers.

Now count characters (including punctuation?). Usually Chinese characters count includes punctuation? We'll approximate. Let's count characters ignoring punctuation maybe. Let's count manually:

E x c e l (Latin letters count as characters? But we can treat them as characters anyway. It's okay.)

I'll count Chinese characters only.

"Excel里有很多图表能帮我们快速看懂数据" -> characters: Excel里有很多图表能帮我们快速看懂数据 = let's count: Excel (5 letters) maybe count as 5? But it's okay. Let's just approximate length ~80 characters. Might be okay.

But we need each paragraph 150-250 characters, not words. So need to ensure each paragraph is at least 150 characters. Let's count more precisely.

I'll write a paragraph with about 180 characters.

Now count characters (including English letters and punctuation). Let's count each Chinese character and punctuation as one. I'll write indices.

I'll rewrite without spaces: "Excel里有很多图表能帮我们快速看懂数据，今天聊聊怎么用Excel做区间分布图。它能把一堆数字划分进几个区间，一目了然地展示每个区间的数量。只要三步，就能把枯燥的数据变成直观的可视化，适合在报表里直接使用。"

8 (space?) Actually there is "Excel里" includes English letters + Chinese "里". Let's just treat each char.

I'll count sequentially:

(space?) There's no space maybe. Actually "Excel里" includes "Excel" then "里". So after "l" there is "里". So continue:

i(7) Actually "里" is a Chinese character, count as 7.

"聊" 27? Actually "聊" appears twice? The phrase "今天聊聊" includes two "聊". So after "聊" we have another "聊". Let's continue:

"聊" 27? Wait we already at 26 for "天". Then "聊" 27, then another "聊" 28.

" l"? Actually "Excel" letters continue: after "用" there is "Excel". So "E" 32, "x"33, "c"34, "e"35, "l"36.

So about 105 characters. That's too short; need 150-250 characters. Need to expand.

We can add more sentences to reach ~180-200 characters.

Add more details: "它把数据分区后，配合柱形图或折线图，能让趋势一目了然。" That's extra.

Let's craft a new paragraph with about 180-200 characters.

I'll rewrite paragraph 1 with more content.

Now count roughly. Let's approximate length:
